This NYE makeout sesh comes two months after Gaga's split with her audio engineer Dan Horton who she dated after splitting from Christian Carino in February 2019 (right around the time all those Bradley Cooper rumours were floating around). Apparently, Gaga and Dan worked on a ton of new music together, with a source telling Us Weekly, "They’re working very closely together at a home studio in Hollywood, and sparks just started flying...They seem like a pretty good match."
Gaga revealed back October that she was single again.
