Well someone’s been doing their crunches!

Lady Gaga showed off her abs in a sexy black leather get-up in her native New York on Sunday.

Late Sunday, the Born This Way singer tweeted about an upcoming run-in with another icon of the city that never sleeps.

“I'm live with @howardstern  2moro morning on Sirius XM,” the multi-Platinum pop diva, 25, wrote. “Big fan. Gonna sing  my face off, and talk s**t w the raddest Hair in radio.”
