was spotted riding downtown on the back of a motorcycle. And guess whom the motor cycle belonged to? Our very own Hangover star Bradley Cooper! Now who wouldn't want to ride the back seat of his Ducati! The question is - why would Lady Gaga be recreating a specific scene from her very own hit song? Sometime ago, rumors surfaced claiming that Bradley wanted to cast her in his up-coming project but Bradley put those rumors to rest stating that they were false. Whatever the case maybe, us ladies would do anything for a chance tobe Lady Gaga right now, that's for sure!
