Madonna Reveals Lady Gaga Turned Down Duet Request

And the feud continues!

Madonna hasn't exactly shied away from taking swipes at Lady Gaga in recent months, and during her concert in Minnesota on Sunday, the pop icon took another jab at the "Born This Way" singer.

"I have the best fans in the world. So take that, Lady Gaga! You know, I invited her onstage to sing with me. But she turned me down. It's OK, I've been rejected before. It builds a little character," she announced onstage to the crowd.

Although Madge didn't reveal exactly when she extended the olive branch, it appears Mother Monster isn't interested in putting an end to the tension anytime soon.

The battle between the blondes ignited after the Queen of Pop dissed Gagaloo for the similarity between "Born This Way" and "Express Yourself."

We think Madonna needs to find a new way to keep her name in the headlines!
