Selma Hayek shows half a nip slip on German show, 'Wetten, Das?' (possibly NSFW)

Salma Hayek on German language show 'Wetten, Das?' wearing a dirndl

Salma Hayek appeared on popular German talk and variety show 'Wetten, Das?' or 'Wanna Bet?' this weekend. She was on to promote her campaign with Pampers and UNICEF to help vaccinate children and mothers in the third world against tetanus.

Celebrities on 'Wetten, Das?' make bets as to whether everyday guests with odd talents can complete out of the ordinary tasks within a certain time limit. Salma lost her bet and had to wear a dirndl, or traditional Bavarian costume. You may recognize dirndls as the outfits worn by Octoberfest waitresses, their bustlines competing for attention with giant mugs of beer. In Salma's case there's no contest.
