Get ready for Britney Spears [1] to crash Jane the Virgin! Spears tweeted the announcement [2] this week, saying, "See u at the Marbella Hotel soon, @hereisgina @jaimecamil! Guest starring on one of my favorite shows EVER @CWJaneTheVirgin #DreamComeTrue." Shortly after, we learned more at the CW Summer TCA: CW President Mark Pedowitz also echoed that Jane the Virgin is one of Spears's favorite shows, and when showrunner Jennie Snyder Urman heard that, she went after Spears for a guest spot. More importantly, we know who she'll be playing: herself! And Spears will be "Rogelio's nemesis." Can't wait to see how Miami's most dramatic resident [3] reacts.
