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.
