Britney Spears has officially left the country. The Circus rolled out of Adelaide and Brit, K-Fed and the crew arrived in Los Angeles last night. She was spotted at LAX with a souvenir from her month Down Under – an Aussie flag-inspired neck pillow - which some Americans have mistaken for a Confederate flag. Um, yeah, not so much. She Tweeted on her arrival, “Just got home. Flew on V Australia. I think these planes might be the most comfortable planes I have ever been on.” [Translation: Thanks for the free flights Richard Branson! Keep ‘em coming!] After nine long months touring (she did it!!) we’re guessing Brit Brit is going to take a well-deserved holiday. The pop princess is also celebrating her 28th birthday today! Happy Birthday, Brit!
