Before publicly stepping out with Michael, Lady Gaga was with audio engineer Dan Horton for three months. They were originally seen at dinner in Studio City, kissing and flirting. They met while working together in 2018, and started dating a few months after Lady Gaga called off her engagement. 

“They have been working on new music, have spent hours of work time together and became really close," a source told Entertainment Tonight shortly after their relationship was confirmed. "They’re working very closely together at a home studio in Hollywood, and sparks just started flying...They seem like a pretty good match.”

But apparently, the two just weren't meant to be. Us Weekly reported on their split, revealing that it was Dan's immaturity that led to their breakup.

“Gaga does want to date again,” the source told the outlet. “Dan was not mature enough for her.”
