Jennifer Lopez [1] can do no wrong! On Tuesday, the singer looked all kinds of sexy when she arrived for her big night at the American Music Awards [2] in LA. Clad in a hot-pink cutout dress, Jennifer was glowing as she strutted down the red carpet. Jennifer may have celebrated her 49th birthday [3] earlier this Summer, but you'd never know it by just looking at her [4].

Jennifer will be debuting a new song [5] from her upcoming film, Second Act, later tonight. "🚨 BIG NEWS!! 🚨 Performing my new single from #SecondAct on the @AMAs THIS TUESDAY! TUNE-IN!," she tweeted. "It's gonna be an AMAZING night." Second Act is a romantic comedy starring Milo Ventimiglia [6] and Vanessa Hudgens [7] and is set to hit theaters on Dec. 14.
