LADY Gaga gave Madonna a taste of her own medicine at her Born This Way Ball in Helsinki last night.

Gaga mimicked her wrinkly rival by flashing her bottom in fishnet stockings and a thong and yelling: “I don’t give a f*** what people say. We don’t give a f

***. We know the truth.”

Madonna — whose last album MDMA featured a song called I Don’t Give A — has been singing Gaga’s song Born This Way at recent live shows in a direct dig.

In return, Gaga also roped in her dancers and a Black Jesus character to send up the Queen Of Pop’s video for 1989 hit Like A Prayer.

Gaga played to 13,000 fans in
the Finnish capital’s Hartwall Areena — the first Euro date of Gaga’s tour which journalists were allowed to review, and the perfect way to get her own back at Madonna.
