The Real Housewives of Beverly Hills star, who was married to Rimes' new husband Eddie Cibrian, wed mixed martial arts manager Darin Harvey on Saturday night (31Dec11) in Las Vegas.
But it seems the New Year's Eve wedding was just a little fun to usher in 2012.
Glanville tells Us Weekly magazine, "To make it legal, I have to go to the courthouse today and I don't think we're gonna. Super fun though!
"We're not gonna stay married, but it was a fun way to start out the new year!"
A source says, "He (Harvey) came along with her to Vegas and they both got really drunk and thought it was a good idea at the time to get married... They kissed for the cameras and that was it. There’s nothing romantically there."
Glanville and Cibrian split and then divorced after his romance with country singer Rimes was made public in 2009. Cibrian and Rimes wed last year (11).
The Real Housewives of Beverly Hills star exchanged vows with Mixed Martial Arts manager Darin Harvey at a wedding chapel in Sin City on Saturday night (31Dec11).
Announcing the news in a series of Twitter.com posts on Sunday (01Jan12), she wrote, "I'm married again - suuuuuuck it!... um he is my best friend but after some beer and strippers he is now my husband! No joke!... Getting my ring tomorrow! Yes I did really do it!... It wasn't planned and we will handle it, but good times!"
However the happy couple may not be husband and wife much longer - Harvey wrote in a post on his Twitter page the same day: "Don't worry @BrandiGlanville and I had a crazy Vegas moment. Getting annulled tomorrow."
Glanville has two children with actor Cibrian, who is now married to country singer LeAnn Rimes. The pair divorced in 2010.
