The pop-star enjoyed a romantic lunch date with audio engineer Dan Horton in Los Angeles on Sunday.
The new couple shared a passionate kiss on the balcony of Studio City's Granville restaurant.
In true Gaga fashion, the singer went braless under a black vest shirt, with hotpants that flashed her bottom cheeks.
Perhaps her perfect opposite, Dan wore a simple black T-shirt and blue jeans as the couple enjoyed their lemonades.
A fellow patron at Granville told People that the couple were "kissing as they spoke really close up."
"She had a table in the front near the sidewalk, so she was clearly okay with being seen. She seemed very happy when interacting with the guy she was with."
Another source said "She seemed confident and in a good place."
Another source told the publication that Gaga didn't mind being seen with the monitor engineer.
"Ironically, she had a table in the front near the sidewalk, so she was clearly okay with being seen. She seemed very happy when interacting with the guy she was with," said the diner.
Horton has worked alongside the singer since November 2018, before her Las Vegas residency.
The Nashville-based engineer has a penchant for performers and was previously married to Broadway star Autumn Guzzardi.
According to his LinkedIn page, Horton owns a company called Audio Engineering Consulting Group and has previously worked with other stars such as Camila Cabello, Bruno Mars and Justin Timberlake.
