Britney Spears had both her parents, Lynne and Jamie Spears, as well as her two sons, Jayden James and Sean Preston, along for an afternoon checking out the sights in Croatia over the weekend. Britney recently kicked off the European leg of her Femme Fatale tour, and she tweeted about her love for Croatia after her show on Saturday. She's already off again, and tonight she'll be taking the stage in Zurich, Switzerland. The tour is going well; though, last week Britney landed herself in a bit of hot water while filming her "Criminal" music video in London. Britney had to issue an apology when the neighborhood's police department got upset over the video's gun wielding and "lawless" themes in the wake of the UK riots earlier this year. Hopefully, it will all be smoothed over before her series of shows in England at the end of October.
