If you wanted to spot celebs in Los Angeles on Friday night, the Troubadour on Santa Monica Blvd was the place to do it!

Guns N' Roses had a concert at the famed West Hollywood venue, and from Bradley Cooper taking his mom, Gloria Campano, to the other A-listers at the show, the place was quite the scene. Kate Hudson, Chris Brown, David Arquette, Jim Carrey and Emily Ratajkowski were among the many celebs we spotted, and a number of them continued partying afterwards.

Guns N' Roses announced the secret show on Friday, and there were only about 300 people at the venue. This was the first time the band has taken the stage together in 22 years, and they performed hits like "Welcome to the Jungle," "Sweet Child of Mine," "Mr. Brownstone," "It's So Easy," "Rocket Queen," along with covers of Paul McCartney and WINGS' "Live and Let Die" and Bob Dylan's "Knockin' on Heaven's Door," reported E! News. Fun fact: The band regularly performed at the Troubadour in the '80s, and they were reportedly discovered there.

The lineup consisted of lead singer Axl Rose and guitarist Slash, who have famously feuded for years, along with bassist Duff McKagan, keyboardist Dizzy Reed, guitarist Richard Fortus, who joined the band in 2001, drummer Frank Ferrer, who joined in 2006, and backup keyboardist Melissa Reese.

The group previously announced a North American stadium tour, which kicks off on June 23 in Detroit and runs through August. They will also be headlining the 2016 Coachella Valley Music and Arts Annual Festival in California later this month.
