Madonna has been making slick comments about Lady Gaga for what seems like months, even going so far as to incorporate a tongue-in-cheek cover of "Born This Way" during performances on her MDNA Tour.

Gaga's had enough, apparently.

“I don’t give a f*ck what people say," Gaga told a crowd of 13,000 people at a concert at Hartwall Areena in Helsinki, Finland last night. "We don’t give a f*ck— we know the truth."

Then she mimicked some of the moves Madonna's been using on stage before launching into a cover of her own. And it was none other than Madge's 1989 hit "Like A Prayer."

Turnabout is fair play, right?
