While chatting with fashion designer Tommy Hilfiger and a group of women ahead of Justin Timberlake’s invite-only concert at the Fontainebleau in Las Vegas, Sylvester Stallone couldn’t keep his hands off his wife, Jennifer Flavin.

The three-time Oscar nominee, 77, was seen standing behind his spouse with his hands around her waist as the longtime couple, who married in 1997, mingled around the luxury hotel before the SexyBack crooner took the stage.

Flavin, the mother of Stallone’s three youngest children, Sophia, 27, Sistine, 25, and Scarlet, 21, wore an off-the-shoulder black gown with sexy lace detailing just above her midriff and a low-cut neckline.

She wore her blonde hair in loose waves that cascaded down her shoulders as she sipped a cold beverage.
