Justin Timberlake [1] may always be the teenage heartthrob of a generation, but Jessica Biel [2] is making it clear that he is all hers [3]. "Get some, @jessicabiel 😳," Justin captioned his Instagram post on Friday, where Jessica is very clearly taking matters into her own hands as she grips his butt. And Justin certainly doesn't seem to mind!

Justin, who was wearing a Man of the Woods [4] jacket, also seemed pretty pleased in the second photo when he turned around to look at the camera and was smiling from ear to ear. So cute! As if Justin's love letter to Jessica on her birthday [5] wasn't cute enough, these photos are just another reminder that they make an adorable couple. You get some, Jessica!
