Security officers at the pair's luxury home in Beverly Hills discovered an intruder in the grounds and detained the woman before handing her over to cops.
A rep tells People.com, "The property is protected by a 24-hour security team that detected and detained the intruder until she was turned over to the custody of Beverly Hills police officers, who arrested her.
"The intruder never entered the actual residence, and did not make any contact with either Ellen or Portia. Ellen and Portia appreciate the fast and effective response of BHPD officers."
"My mother would freak out about me dating women... She'd start panicking and saying, 'What if they find (media) out...? I'd say, Mom, relax, it's not as if I'm dating Ellen DeGeneres, for God's sake.'" Actress PORTIA DE ROSSI on her mum's concerns about the actress' homosexuality. De Rossi is now married to DeGeneres.
"We were lucky because it was the same weekend that Brad (Pitt) and Angelina (Jolie) got together." PORTIA DE ROSSI on the media break she and lesbian partner Ellen De Generes got when they went public with their lesbian romance.
The lesbian feminist hadn't 'come out' about her sexuality when she shot the saucy stripping scene for Ally McBeal - and she felt humiliated standing there in nothing but lacy underwear.
She tells Bust magazine, "The show was a huge break for me, and of course I wasn't going to make waves... but I was definitely shocked and disappointed that I'd gone from this really professional, hard-working woman to someone who just strips down to her underwear begging her boss to sleep with her.
"I mean, as a feminist, it was revolting to me. And it damaged me, I think, because I realised I had no control. I just felt very cheapened by it."
Pregnant pop star Pink was the first celebrity to show up, confessing, "I'm here because there's cake..."
The singer then recalled a time before DeGeneres "became too famous" when they used to party and drink together.
Pink then revealed she's her unborn child's "baby momma".
She then got serious and said, "In a world that focuses so much on what's dark and what's mean, you are a constant light for me, for all of us... I laugh at you every day."
DeGeneres, who turned 53 on Wednesday (26Jan11), was then shown a funny video message from her partner Portia DeRossi, performing a windswept version of Happy Birthday dressed as Marilyn Monroe.
The surprises continued when Roberts showed up and a blindfolded DeGeneres had to guess who the mystery guest was. Roberts whispered her answers to the host's questions to a nurse who was also celebrating his birthday as a guest on the show.
The movie star finally lifted DeGeneres' blindfold, prompting the host to scream, "Wow!" It was Roberts’ first appearance on the show.
Touched DeGeneres insisted on going to a commercial break, so "I can compose myself".
The two women chatted and when the host revealed she had more surprises, Roberts joked, "If I'm the warm-up... Obama!"
The big wow for the TV star was when one of her favourite men, Colin Farrell, appeared.
The Irish movie star brought out Ellen’s birthday cake and thrilled her with a lingering kiss, before thanking De Rossi, who was in the audience, for her years of understanding.
When Roberts confessed, "I’m deeply uncomfortable," Farrell quipped, "Try coming out after Julia Roberts for uncomfortable."
He presented his friend with a T-shirt bearing a photo of the two of them together on a previous show.
Child star Jaden Smith was the final guest; he gifted the birthday girl a well in her name that will provide clean drinking water to an African village for 20 years.
The Karate Kid star said, "It has, like, a GPS, so you can go on GoogleEarth and look at it."
"I don't know when I'll use it. I honestly changed it thinking, 'Oh, that's nice, I'll have a Social Security card and passport with DeGeneres on it.' But it was really important for me to take her last name." Actress PORTIA DE ROSSI on her name change to honour partner Ellen DeGeneres.
The former Ally McBeal star, who is married to comedienne Ellen DeGeneres, recently admitted to radio personality Ryan Seacrest she would consider taking part in the competition, after learning TV producers were keen to have her dance opposite a professional female on the next season of the hit programme.
But De Rossi has since decided against the idea and rejected a formal offer from Dancing With the Stars.
Her representative tells Eonline.com, "Yes, she was asked but she declined."
If you missed out on Better Off Ted, shame on you. What was one of the funniest and smart television shows of the past three years (hell, five years) was regretfully seen by too few too late. Luckily, it is available for streaming on Netflix which you should be doing right now.
Also, the show's creator, Victor Fresco (BEST NAME EVER), has started developing a new show centered around suburban life called Sunnyside. If he can bring the same wit and charm to the suburbs as he did to the business meeting, I’m watching this show from start to finish. The unusual thing about this show, for Fresco at least, is that it is an adaptation of a Swedish television show Solsidan. Which honestly sounds like something Veridian Dynamics would create.
Also: this is the best picture I could find of Fresco and all things considered, I had to include Portia de Rossi to balance it out.
The Aussie actress married American talk show host Ellen DeGeneres in 2008 and has recently turned her attentions to campaigning for gay rights.
De Rossi has been back Down Under this month (Nov10) as part of a promotional tour for her new book Unbearable Lightness: A Story of Loss and Gain, and she took the opportunity to address the topic of same-sex marriage during a radio interview.
The Ally McBeal star admits she thought Australia would have been one of the first countries to legalise same-sex unions and she is adamant Prime Minister Julia Gillard has let down the public by failing to act on gay marriage.
She tells 702 ABC Sydney, "I always thought Australia would pass this equal rights law long before America would. I'm a little bit disappointed with the new Prime Minister. I'm hoping that Australia will be a leader on this."
The former Ally McBeal, who is married to comedienne Ellen DeGeneres, is currently on a promotional tour for her memoirs, Unbearable Lightness: A Story of Loss and Gain. The book chronicles her battles with anorexia and her sexuality.
But the star has caused controversy in Australia after reportedly insisting that no men interview her.
David Koch, the host of hit morning show Sunrise, reveals he was furious when the actress' team asked for his co-host, Melissa Doyle, to chat to the star via satellite from Los Angeles - accusing the actress of "discrimination".
He tells the Sydney Morning Herald, "If a male said I don't want to be interviewed by a woman, there would be a massive outcry of discrimination.
"Obviously she has got issues and I feel quite sorry for her... I admire what she and Ellen have done for community tolerance and inclusiveness. But it is a real contradiction for what she stands for, which really surprises me. Maybe she is uncomfortable with men, but she plays opposite male leads."
De Rossi has also reportedly turned down the chance to chat to male radio double-act Hamish Blake and Andy Lee on their hit show.
