Stereo divas? We hear that Madonna and Lady Gaga have discussed performing together in a dual concert extravaganza similar to the Face 2 Face shows that piano men Billy Joel and Elton John did a few years back. Gaga’s reps didn’t respond to our requests for comment, but Madonna’s spokeswoman Liz Rosenberg replied that the Material Girl’s manager “laughed” when she ran our item by him. She then instructed us to “go to the title of Stevie Nicks’ new album for the answer.” That would be “In Your Dreams.” D’oh!
