Lady Gaga surprised fans on Thursday (May 28) by serving up "Sour Candy," her wildly-anticipated collaboration with Blackpink, and it's safe to say both Little Monsters and Blinks are on a sugar high.Arriving on the eve of Chromatica's release, the track sent both pop fandoms into a frenzy on social media over its slinking beat and stuttering chorus."Gaga x Blackpink is a huge serve! #SourCandy is such a cute bop, they did that!" one fan tweeted, while another cleverly resurrected the recent viral meme featuring Lisa's legs with a photo from Gaga's Super Bowl halftime show rehearsals, writing, "Me singing both parts of #SourCandy by Lady Gaga and Blackpink."Several Blinks pointed to both Rosé and Lisa's vocals in the track's opening verse.
