It's possible that Britney is taking fashion clues from North West, and her cousin, Penelope Disick. On Wednesday, Kim Kardashian posted a picture of the two cuties with a new friend they made on their epic St. Barts vacation, writing, "Little mermaids." Meanwhile, Britney Spears is about to go from sunscreen to the small screen, when she guest stars on The CW's Jane the Virgin in the upcoming season! Showrunner Jennie Snyder Urman had the scoop for ET. "We've got Britney Spears!" Urman gushed. "We're just so excited, and I'm still freaking out." The executive producer dished that Spears will be playing an "exaggerated version" of herself in episode five of season two. "It's in the same sprit of when Paulina Rubio came on [to the show in season one]," she said. "It was still Paulina Rubio, but it was a fictionalized Jane the Virgin version."
