Joining Joe in Vegas was little brother Nick Jonas and his girlfriend Olivia Culpo. Joe and Nick showed off their muscles at Encore Beach Club at Wynn Las Vegas on Friday and then on Saturday they hit up XS The Nightclub at Encore Las Vegas. How great does Joe’s cake look?

On Friday, Joe also caught up with his “Kingdom” co-stars Jonathan Tucker & Matt Lauria at the inaugural event for BKB, Big Knockout Boxing, at the Mandalay Bay Events Center. How great does Nick look in his vest and tie?

Happy belated birthday Joe!
