After her performance, Gaga made sure to mingle with fellow performers and nominees seated in the arena. She was captured having a sweet reunion with longtime friend Donatella Versace.

Gaga was also seen cozying up to BTS member V, who was looking handsome in all-black. She placed her arms on the young man’s shoulders and enjoyed a brief heart-to-heart before kissing his cheek.

She appeared to be having an extra fun chat with Lil Nas X, who she took a selfie with mid-show. She puckered up for the camera, while the 22-year-old hitmaker showed off his custom grill.

The win marks the 13th for Lady Gaga from 34 nominations and the 19th for Tony Bennett from 41 nominations.

Their album was also nominated for Album of the Year along with three awards for their song I Get A Kick Out of You – Best Music Video Of the Year, Best Pop Duo/Group Performance and Record of the Year.

Though Tony was invited to Sunday’s ceremony,  Bennett’s son Danny told Variety that he would not be attending due to his health and continued struggle with Alzheimer’s disease.

‘Tony is beyond thrilled, particularly at the young age of 95, to once again be recognized along with his musical collaborator and dear friend Lady Gaga by the Recording Academy for their album Love for Sale,’ Danny began in his statement to the outlet.

‘To have the album nominated in six categories including Album of the Year and Record of the Year is an incredible honor,’ he added.

‘Although the producers had invited both Tony and Gaga to perform in Sunday’s Grammys broadcast, it is unfortunate that due to his continuing struggle with Alzheimer’s, he was not able to accept,’ Danny continued.

‘It was decided that it would be fitting for Lady Gaga to perform on her own to represent for both of them,’ Bennett’s son, 68, explained.

He concluded: ‘There is no doubt, that she will offer up an impeccable performance from Love for Sale, which is Tony’s final album. He will be cheering her on as he watches from his home in New York City.’
