Lady Gaga Stepped Out in an Ab-Baring Sweatsuit and Nighttime Sunglasses

Mother monster traded in her 9-inch platform boots and angel wings for a comfy-chic sweatsuit and sneakers following her opening performance with Tony Bennett.

On Tuesday night, Lady Gaga appeared to be very happy with her and Bennett's first performance of the much-talked-about concerts series at Radio City Music Hall in honor of Bennett's 95th birthday and "last N.Y.C. performances," according to DailyMail. Gaga exited a black SUV and returned to her N.Y.C. hotel with her hands in the air and a big smile on her face.

The "Bad Romance" singer stepped out in beige joggers and a matching ab-baring sweatshirt, which she wore with the hood up. Despite the fact that it was obviously nighttime, the star of the upcoming highly anticipated film House of Gucci wore black cat-eye sunglasses. Instead of sky-high platform boots, Gaga wore white Nike sneakers with black socks.

The singer has spent the last week or so traipsing around New York City making quite the fashion statement in preparation for the concerts. From leotards and turbans to a pantless poncho, Gaga brought her usual head-turning style to the Big Apple.

The Star is Born actress was asked to perform with the iconic jazz singer for his 95th birthday in a series of special concerts, titled "One Last Time: An Evening with Tony Bennett & Lady Gaga." Given Gaga's reaction, it seems like the opening night went off without a hitch, and the next performance takes place tomorrow, Aug. 5. She initially announced the special concerts on Twitter.

"I am so honored and excited to celebrate Tony's 95th birthday with him at these special shows," she wrote.
