Mick Jagger and Courtney Love hooked up for a karaoke duet on the Oasis song “Wonderwall” at a post-Oscar bash Sunday night.

A guest leaving the party described it for the British tabloid The Mirror, calling it “an absolute scream” and “a real crowd-pleaser,” with guests “crowded around, clapping and singing along with them.” Mick was said to be “really giving it some swagger,” while Courtney was “absolutely loving it.” Leonardo DiCaprio and Bradley Cooper were among those who witnessed the wildness, which took place at an unnamed Beverly Hills location.

Afterwards Courtney tweeted to Mick: “Alright man, that was fun.”
