In perhaps the most unlikely of duets, Mick Jagger and Courtney Love teamed up for a karaoke performance of Oasis' "Wonderwall" at a post-Oscars part in Beverly Hills.

"It was an absolute scream," an insider told The Mirror.

"Guests were crowded around, clapping and singing along with them.

It was a real crowd-pleaser. Mick was really giving it some swagger, and Courtney was absolutely loving it."

According to the insider, Jagger was his typical self during the performance, utilizing his trademark strut and pursed lips look.

He stole the show according to reports. The crowd reportedly erupted into cheers when Love and Jagger finished up.

Over the weekend, the 71-year-old Jagger was also pictured partying at Rihanna's birthday with Jude Law's ex-girlfriend Alicia Rountree, 28.
