Lady Gaga's 'Poker Face' will be Palms Casino's ad campaign

Christopher Walken and South Park's Cartman aren't the only ones who love Lady Gaga's 'Poker Face.'

The Palms Hotel and Casino in Las Vegas will use her hit song in their latest ad campaign. 

Which is amusing since we only recently found out that the song is about her fantasizing about having sex with women while making love to her boyfriend.  What happens in Vegas, gets fantasized about?
