The Angel star recently confessed to cheating on his ex-Playboy Playmate wife Jaime Bergman with an unnamed woman, and admitted he was forced to come clean about the affair after his mistress threatened to sell her story to the media.
Online gossips named Uchitel - the woman who sparked the Woods affair scandal - as Boreanaz's mistress, but she initially refuted the claims, stating, "I am not in communication with him and do not wish to be. I have made no claims against him and do not plan to assert any."
But, after a string of angry texts allegedly sent between the pair were leaked online, Uchitel's lawyer Gloria Allred has revealed her client did have a relationship with the TV hunk, and claims the star "treated her as his girlfriend" during their torrid romance.
A statement from Allred reads, "(Rachel) understood that he (Boreanaz) was unhappy in his marriage and had been for some time and she had reason to believe that he intended to separate from his wife.
"He treated her as his girlfriend and also took her out in public. He called her between takes when he was taping his television show and put her on the telephone with his friends and his son. He even stayed with Ms. Uchitel when he came to New York for press tours."
And Allred insists her client ended the relationship because "she felt that he had not been completely truthful with her and she no longer trusted him."
Bergman, who has two children with Boreanaz, recently revealed her personal pain after hearing of her husband's infidelities. She said, "I'm still angry. I'm still mad. I am still hurt. It took a crisis, it took infidelity to get us off our a**es and work for what we want."
The couple is fighting to save the marriage.
TIGER WOODS' golf comeback has hit a stumbling block after sustaining a neck injury which has forced him to quit The Players Championship in Florida. The disgraced sports star, who bowed out of the competition on Sunday (09May10), has been working to rebuild his career since returning to the green last month (Apr10) following a brief hiatus prompted by the news of his infidelities in November (09).
Boreanaz, who played Angel in the cult show and it's TV spin-off, has opened up about his bad behaviour to the upcoming People magazine.
He reveals he has been unfaithful to his wife, Jaime Bergman, and the two are currently trying to save their marriage - after a former mistress threatened to go public with their affair.
He confesses, "Our marriage has been tainted with my infidelities. I just want to be open and honest. I was irresponsible.
"I was associated with a woman who I was involved with and had a relationship with. She asked for money. I felt as though I was being blackmailed or there was some sort of extortion."
Boreanaz joins Tiger Woods, Sandra Bullock's estranged husband Jesse James and Take That star Mark Owen on the list of famous bad boys who have been forced to come clean about their infidelities in recent months.
The actor hopes the mistakes he has made don't end his marriage: "We're working on repairing what has been damaged so badly."
Boreanaz and actress Bergman have an eight-year-old son, called Jaden Rayne, and a daughter, Bardot Vita Boreanaz, who was born last summer (Aug09).
This is his second marriage. His first union with Ingrid Quinn ended in divorce after just two years in 1999.
Waitress Jaimie Grubbs will lead a cast of other celebrity mistresses, who are looking for real love.
Details of the other ladies involved in the show, which will be presented by U.S. TV personality Michelle Harris, are being kept under wraps.
Harris' spokeswoman tells WENN, "It's going to be a show full of drama."
The title of the dating programme has yet to be confirmed.
One of TIGER WOODS' alleged mistresses, JAIMEE GRUBBS, spent Wednesday night (14Apr10) behind bars after she was arrested on three outstanding warrants for driving on a suspended license. The Los Angeles cocktail waitress was released on $30,000 (£20,000) bail on Thursday morning (15Apr10) and will appear before a judge on Thursday afternoon.
Just days after Woods completed his triumphant return to golf following his cheating scandal, U.S. news show Entertainment Tonight reports Nordegren, who failed to show at his U.S. Masters Tournament comeback, is close to filing for divorce.
Correspondent Kevin Frazier, who has links to Woods, says, "For weeks now there have been rumours that Tiger Woods and Elin Nordegren might reconcile and save their marriage. It was believed by going to sex rehab that Tiger had done just enough to keep his family together. But sources have told me that the marriage is indeed over.
"Evidence? Well, the fact that Elin was on a plane, in the air, headed to Arizona during the final round of the Masters. Usually, with her husband in contention at his biggest tournament, she would be there waiting for him in case he won; instead she made a plan so that she would be in the air while Tiger was playing.
"The couple hasn't spoken for quite some time and it is believed that all they have to do is work out a few more details on their divorce and they can sign the divorce decree and both can move on with their lives."
The couple's marriage problems hit the headlines in November (09) when the first of many alleged mistresses came forward with claims they bedded Woods during his marriage.
"My advice to Tiger (Woods) and this is the same advice to any married guy: 'Just come home as quick as possible, and you will stay outta trouble.' So, when I'm done with this show, I will get in a helicopter and go straight home, so no miscellaneous ho will get me between here and the dressing room." CHRIS ROCK tells late-night chat show host GEORGE LOPEZ he stays faithful by going home.
"My people called and said I might have to tame my tweets a little. So here goes... I'm going to make a sandwich now. peanut butter." JIM CARREY makes light of the fuss surrounding his weekend Twitter.com remarks about TIGER WOODS' cheating scandal.
The Mask star stunned Hollywood and fans when he announced his split from his girlfriend of five years on his Twitter.com blog last week (begs05Apr10), and a pair of bizarre 'tweets' about Tiger Woods' marriage troubles, posted over the weekend (09-11Apr10), had many fearing the funnyman was losing his mind.
In a post on Friday (09Apr10), Carrey wrote, "Tiger Woods owes nothing 2 anyone but himself."
He then turned on the golfer's scorned wife, Elin Nordegren, declaring, "No wife is blind enough to miss that much infidelity. Elin had 2 b (sic) a willing participant on the ride 4 whatever reason."
Carrey later attempted to explain his comments in another 'tweet', adding, "I want 2 make it CLEAR that I do not condone infidelity at all, but 2 some degree the responsibility 4 it is shared by both people."
The actor's outspoken comments have sparked worries about his mental state, but the star insists he's just thinking more clearly than he ever has before.
He writes, "Some folks out there are worried that I stay up too late. This is no breakdown! It's a breakthrough! And if you'll just loosen these straps, I'll show you the difference!"
The movie star left Twitter followers puzzled when he waded into the Woods cheating scandal by claiming the embattled golfer's wife must have known about his infidelities.
In a 'tweet' on Friday (09Apr10), Carrey wrote, "Tiger Woods owes nothing 2 anyone but himself."
The actor, who also took to Twitter.com to announce his split from girlfriend Jenny McCarthy earlier in week (beg05Apr10), then turned on the golfer's scorned wife, Elin Nordegren, declaring, "No wife is blind enough to miss that much infidelity. Elin had 2 b (sic) a willing participant on the ride 4 whatever reason."
Carrey's comments sparked much online debate over the weekend, and now the funnyman has taken to Twitter.com in a bid to explain himself.
He adds, "I want 2 make it CLEAR that I do not condone infidelity at all, but 2 some degree the responsibility 4 it is shared by both people."
