The party went down at Oil Can Harry's in Studio City, and Ronson and Gaga weren't just there to mingle, they also got in the DJ booth for a remix of their Grammy-winning song, "Shallow" from "A Star is Born."
Gaga, who was seen dancing to her music, took home three awards while Ronson claimed two of his own during the awards ceremony Sunday night at Staples Center in Los Angeles. In attendance at "Club Heartbreak" were some of the hottest stars, including Adele, Katy Perry, Troye Sivan, Charli XCX and the ladies from Haim. The night was flowing with Absolut Elyx who sponsored the event.
For the stars that weren't able to make the trek to "Club Heartbreak," there was also the Republic Records part at Spring Place in Beverly Hills. That crowd included Paris Jackson, Stevie Wonder, Fat Joe, Joe Jonas and Sophie Turner.
