Jennifer Lopez and Casper Smart Have a Sexy Date at the AMAs Afterparty

Jennifer Lopez and boyfriend Casper Smart made a hot appearance at the afterparty for the 2015 American Music Awards, held at the Microsoft Theatre in Los Angeles on Nov. 22, where the Puerto Rican singer and actress hosted and performed. The couple, who has been dating on and off for the past four years, stayed closed as they posed for the cameras with J Lo in yet another revealing outfit of a crop top and tight skirt — we'd be fools to expect anything else. At the celebration, J Lo let loose, dancing and sipping Champagne with old pals, like P. Diddy.

Casper has been by J Lo's side at all major red carpet events this year, joining her from Heidi Klum's Halloween party to her weekend at the iHeart Radio Music Festival in Las Vegas, so it was no surprise to see him sitting from row at the award show with J Lo's friend Demi Lovato. Recently, Jennifer called the dancer "her love" on an Instagram post, showing their bond is tighter than ever.
