Landon Barker and Charli D’Amelio Spotted Holding Hands In New York City

It’s official. Landon Barker and Charli D’Amelio are an item.

On Tuesday night, the new couple was spotted holding hands after leaving Machine Gun Kelly’s Madison Square Garden afterparty in New York City.

The pair were in New York for Landon’s surprise appearance on stage at Machine Gun Kelly’s sold-out show. Both musicians performed “Die in California” from MGK’s Mainstream Sellout album.

At the same time as the performance, TMZ broke the news that Travis Barker had been hospitalized.

PEOPLE editor Nigel Smith was at the concert. He described Landon as “very emotional” during the performance of his second song, which was dedicated to his friend Cooper Noriega who recently passed by suicide.

“Landon came out during the song and seemed to be working out some demons,” he said. “They hugged onstage during the performance, singing and shared an emotional moment at the end of the song before Landon walked off.”
