Lady Gaga appeared on Jimmy Kimmel Live! on October 1st to promote her upcoming film ''Joker: Folie à Deux'' and its companion album ''Harlequin.'' 

During the interview, she captivated the audience with stories about her engagement to Michael Polansky. Gaga shared that her fiancé proposed after a hiking trip, asking for her permission before popping the question. She humorously revealed that they’ve even discussed the possibility of a simple courthouse wedding followed by Chinese takeout instead of a lavish celebration.

   

Gaga also opened up about the creative process behind Harlequin, explaining how the concept for the album was conceived alongside Polansky. To top off the evening, she performed "Happy Mistake," a song from the album that reflects her signature emotional depth and connection to her Harley Quinn role in the Joker sequel. This performance marked the first live rendition of the track, further blending her music with her portrayal of the iconic character.
