He's someone that they want to know: Rumer Willis, Lauren Conrad and Audrina Patridge all came out for a mini-concert by Gotye at The Sayers Club in Los Angeles on Monday.

Willis hung out in the V.I.P. area, but once the show began she made her way toward the stage, and afterward, greeted Gotye. "He leaned in to whisper something to her that made her smile sweetly," an onlooker tells PEOPLE. "She looked almost shy." Conrad, there with fellow Hills alum Stephanie Pratt and two other girlfriends, also grabbed a table in the V.I.P. section, enjoying appetizers, the signature Pineapple Smash cocktail – and lots of conversation with her pals.

Patridge also got to meet the musician, snapping a photo with him after watching the concert from the floor (and avoiding Conrad throughout the evening). Also there: Mirror Mirror's Lily Collins and former American Idol winner Kris Allen, who snacked on a mini burger and flew under the radar. – Jessica Wedemeyer
