Lady Gaga and Foo Fighters performed an exclusive show in San Diego on Thursday (January 8).

The acts - who were joined by Tony Bennett and Aloe Blacc - played the 600-capacity Belly Up venue.

It was held in honour of global talent agency William Morris Endeavor, who have all four artists on their books.

The show was invite only and its line-up was kept largely secret until show time.

Speaking on Instagram today (January 9) about the gig, Lady Gaga said:

"The Foo Fighters were so incredible tonight, monster fury rock n' roll, 20 years of locked precision.

"Can't stop screaming, almost took my pants off Dave playing guitar with an empty shot of Jägermeister. Glass to the strings."
