Jessica Alba showed up in a celebrity kissing booth on Tuesday night's Jimmy Kimmel Live! and offered up smooches to both male and female fans.

Armed with rubber gloves and a glass wall, the 31-year-old Sin City star got in on a little girl-on-girl action per the late-night host's request, but later teased one of her other kissing booth patrons with a peck.

Alba was on the show to promote her new book The Honest Life and her movie Escape From Planet Earth.
