Jennifer Lopez rocked the crowd at the American Music Awards Sunday night -- along with backup dancer and rumored boyfriend Casper Smart -- but her party didn't end on the stage.
Lopez hit up her own AMA after-party at the Greystone Manor Supperclub where she spent the night dancing and enjoying the scene with Smart.
According to Us Weekly, Lopez and Smart hung out in a private booth together for most of the party, and the singer wasn't shy about showing some PDA with her her rumored beau.
Lopez, who split from husband Marc Anthony over the summer, has played coy when it comes to talking about her new relationship with Smart, but sources confirmed to PEOPLE that they are definitely seeing each other.
"Yes, they are dating and having a good time," a source revealed earlier this month. "They've been getting more open with their flirting for weeks."
So are things getting serious between the pair? Not quite. Other sources referred to their situation as just a "fun fling."
