Britney Spears touched down in Mexico last night with her boyfriend Jason Trawick. They went south in order to celebrate Britney's 29th birthday, which was last Thursday. It was a well-timed getaway, as Britney had to deal with some drama during the previous week — she made a colorful statement on Twitter after a tabloid alleged that she suffered from domestic abuse. Now she and Jason can unwind in Puerto Vallarta at the private villa he rented, and maybe she'll even show off her famous bikini body one last time in 2010.
