The "Gimme More" singer spent Thursday with music producer JR Rotem - an old ex that we haven't seen with Brit since Alli got served by K-Fed's lawyer in early August! The two hit up the Viceroy Hotel in Santa Monica, but earlier (in the video below) Britney showed up at Malibu Cinemas to see The Heartbreak Kid - she asked us "What day is today?" - and was heartbroken to find out the movie hadn't open yet. Go see it tomorrow, Brit!
