Say what you will about Lady Gaga, but girlfriend is killing it with duets lately!

She's on the road with Tony Bennett for tonight's concert at Meadow Brook Music Festival (7/27), but before that, she rocked it out with U2 last night dressed in typical GaGa garb. Check out the performance, do you think there might be a U2/Gaga collab in the works? One can hope!

But alas, while we all wait for that, check out one of my favorites, when it comes to Lady Gaga collaborations with the Rolling Stones. I hope to see more and more of these. Get it Gaga!
