Brittny Gastineau Goes Topless In Pool, Talks Kim Kardashian Rift (NSFW PHOTO)

After catching best friend Kim Kardashian's bouquet at what we all thought was the wedding of the year, Brittny Gastineau is no longer speaking with the friend from whom she was once inseparable. But the pair's rift didn't stop the 28-year-old from celebrating her birthday weekend with a little topless pool time at the Mexico home of "Girls Gone Wild" founder Joe Francis.

"Brittny doesn't want to talk about what happened with Kim," a friend of Gastineau's told me. "She is hoping, over time, that the two of them become close again. Every friendship goes through its ups and downs but these two are like sisters. I'm sure they will work everything out."

Lisa Gastineau, Brittny's mom, confirmed to Radar Onlinethat the friends are no longer talking: "Brittny was very concerned about Kim's decision to jump into this marriage, and she expressed that to her. ... She is very hurt that Kim has frozen her out of her life right now."

Nothing gets your mind off missing your best friend more than topless pool fun!
