Britney Spears went all out and brought her whole family on stage to close out her Femme Fatale tour in San Juan, Puerto Rico, last night. Britney celebrated her 30th birthday as well as wrapping up her tour at a big bash over the weekend, and she spread the love on Twitter with lots of thank-yous for her crew and dancers. Last night was her final show, and she closed things out by bringing her sons Sean Preston and Jayden James, boyfriend Jason Trawick, sister Jamie Lynn Spears, mom Lynne Spears, and niece Maddie all out on stage. Brit has had an amazing year and she's looking fantastic as well — in fact, she's currently in the lead in our best bikini body of 2011 poll!
