Gwen Stefani and Blake Shelton showed off some major PDA during a romantic date night full of kisses and even some booty-grabbing.

E! News has obtained exclusive photos of the couple enjoying a double-date at Casa Vega Mexican restaurant in Studio City, Calif., on Tuesday night during which they simply couldn’t keep their hands off each other.

A source tells us, “They were there with another couple and were waiting for valet for about five minutes. He kissed her twice and was pretty much grabbing her butt as he did.”
