Caitlyn Jenner took the stage at the Greek Theatre in Los Angeles on Friday night, introducing Boy George at the Culture Club concert to rousing applause from the crowd.

“Caitlyn Jenner in the house for her first Boy George concert!” she said during the surprise on-stage appearance. “This is going to be a good group. Thank you so much. Enough about me. Thank you for being here tonight. This is so much fun for me. Let’s hear it here at the Greek Theatre for Boy George! Let’s get it going!”

Boy George told the audience he expected Jenner, 65, would make the crowd go wild.

“I expected a standing ovation for her and I wasn’t disappointed,” Boy George said after thanking Jenner for the introduction, according to Entertainment Tonight. “We need to celebrate the kinds of changes that are happening.”
