That was just a mini innofensive lap-dance lol I would like to watch more :P If she chose a girl its because she like to shock people. And I think she's bisexual, which is great!! The song Te amo, the fact she tell radio that Cheryl Cole is the most beautiful girl in the world, she touch the butt of Nicki Minaj in show. Rihanna like girls, and she's not only doing this for fun, its also to make people more open with that stuff. It was hot I think.. and she's not the only one.. Gaga, Madonna and a lot of others singers like girls..
