Damn, girl! Skinny bitch Lady Gaga hit up Z100's NYC studios on Sunday to promote her new album Perfect Illusion.

The singer signed autographs, posed with fans and even kissed one lucky dude on the lips!

Her supporters were overwhelmed by Gaga's sexy short shorts and barely-there crop top, which exposed her black lace bra. Wow! The Lady's quite a lady!

Recently, when asked if her new album is about her breakup from long-time love and fiancé Taylor Kinney, Gaga responded that it wasn't despite lyrics that go: "It wasn’t love, it wasn’t love, it was a perfect illusion" -- she recently told the UK's Sun newspaper: "I think it’s both sides: it’s not really from the woman’s perspective, this song. It was important to me that men, when they heard this song, felt connected to women even though the song is essentially about a barrier between us." She was careful not to talk about heterosexual love but all types of relationships.

She's also been talking about pills recently ... following the release of her 2013 album ARTPOP, she shocked fans by revealing she was taking medication to deal with depression and now Gaga is admitting she continues to take meds to stay balanced. She recently told The Daily Mirror: "I take medication,' she said. 'I'm not saying I feel good because of the medication - I wouldn't encourage young people to take anti-depressants or mood stabilisers. I admit to having battled depression and anxiety and I think a lot of people do."

So many revelations! We just hope Gaga's in a good way and that she keeps strutting her stuff in crazy sexy get-ups and continues making awesome pop music that sticks in our brains. And we hope her brain (and her heart) are healthy!
