Jennifer Lopez told her American Idol buddy Ryan Seacrest this morning that she's officially leaving the show. J Lo confirmed her exit from Idol on Ryan's radio show this morning. Jennifer's been a judge for two seasons, compared to Ryan's 10 years as host. She said, "I honestly feel like the time has come that I have to get back to doing the other things that I do — that I put on hold because I love Idol so much . . . we had an amazing run." One of the things Jennifer prioritizes is her relationship with Casper Smart. Things are going great between them, and he even shared a picture of him and Jennifer at the beach. He tweeted yesterday, "Me and the Bear [Jennifer] wake-boarding in Long Beach. Got up her 1st try." Jennifer's announcement comes just after her fellow judge Steven Tyler also said he's no longer going to be a part of the Fox program.
