Jessica Alba was "hot and bothered, but not in a good way" when she agreed to step into a Celebrity Kissing Booth during a skit on Tuesday night's (12Feb13) Jimmy Kimmel Live! show and smooch lusty fans behind glass.

The pretty star agreed to place her hands and arms in long rubber gloves extending from the booth, which was located outside Kimmel's studio on Hollywood Boulevard in Los Angeles, so she could give lucky guys and girls a taste of what a real kiss from the Sin City star would be like.

The first kiss went to two female fans, who confessed it had always been their dream to kiss the actress.

The next one was a South African tourist, called Lifa.

Alba then rejoined her pal in the studio for a cooking segment with barbecue chef Bobby Flay.
