Lady Gaga has been rocking some seriously skin-baring outfits lately, and Tony Bennett's 90th birthday celebration at Radio City Music Hall was no exception. The songstress stepped onto the red carpet in an LBD, featuring a sexy thigh-high slit, and a narrow-cut neckline, showing off the tattoos on her ribcage and some serious side boob action.

Gaga paired her va-va-voom look with intense eye makeup, a sleek updo, and strappy black Ruthie Davis heels. She performed at the variety show along with Michael Bublé, Diana Krall, K.D. Lang, Andrea Bocelli, Stevie Wonder, and of course Tony Bennett, one of her closest friends and colleagues.

Gaga and Bennett have worked closely together in the past, releasing an album of songs entitled Cheek to Cheek, and even going on a joint world tour for the album.

From her hot pants and crop top look at the Brandon Maxwell show, to her many skimpy street style looks from New York Fashion Week, the newly single Mother Monster is clearly ready to mingle. Plus she recently announced her new album, titled Joanne, coming out on October 21st. Gaga has a big month ahead of her and we can't wait to see what outfit she steps out in next!
