Jennifer Lopez American Idol Elimination Show Pictures

Jennifer Lopez waved hello to the American Idol audience as she took her judging seat for the elimination show in LA last night. Contestant Heejun Han was sent home on the episode, which also featured a performance by last year's winner Scotty McCreery and Nicki Minaj.

J Lo switched gears back to her own music this morning, sharing her new track "Dance Again" on Ryan Seacrest's radio show. She'll premiere the video for the new song on AI next Thursday. J Lo will likely sing the new jam along with some others this Summer when she performs for the first time in Brazil. She announced plans to headline two dates of Sao Paulo's Pop Music Festival during a recent trip to the country with boyfriend Casper Smart. And it looks like he's planning to join her again, since he tweeted, "Thanks again Brazil for being so welcoming. See you in the Summer!"
