Jennifer Garner gives the phrase "sweet kisses" a whole new meaning, according to her Arthur co-star Russell Brand.

"There's a brand of red-velvet cake, her mouth is made of that," Brand, 35, tells "She smashed you in the mouth [in] those kissing scenes."

The Get Him to the Greek actor, who wed songbird Katy Perry last year, goes on to suggest Garner's hubby might not be keen on her kisses.

Says the star, "If I were Ben Affleck, man, I'd be pissed off!"
