Have Lady Gaga and rumored boyfriend Daniel Horton called it quits?
Gaga, 33, sparked speculation of a breakup while attending her longtime makeup artist Sarah Tanno’s bachelorette bash on Friday.
Sharing a selfie of herself and the bride-to-be, the singer — who also shared that she was “in a lot of pain” after suffering a nasty fall the previous day — captioned it, “an about to be married woman and me, a single lady.”
The “Shallow” singer and the audio engineer, 37, were last seen together at a concert for The Cure and the Pixies in September.
A rep for Gaga did not immediately respond to PEOPLE’s request for comment.
Gaga and Horton first sparked romance rumors in July, after they were photographed kissing during a brunch date in Los Angeles.
A source told PEOPLE at the time that the pair dined for about an hour and were deep in conversation. “They were kissing as they spoke really close up,” said the source.
“Ironically, she had a table in the front near the sidewalk, so she was clearly okay with being seen,” the source added. “She seemed very happy when interacting with the guy she was with.”
