They’re both known for their penchant for the Los Angeles nightlife, and on August 9 Ashlee Simpson and Shenae Grimes were spotted at the Troubador club.

The “Pieces of Me” songstress and her “90210” gal pal hit up the West Hollywood hot spot to see John Mayer perform one of his well-known surprise gigs.

And as they left the venue, both Ashlee and Shenae looked like they’d just witness a killer show thanks to the “Your Body is a Wonderland” crooner.
