Holly Madison was always the No. 1 girlfriend in the Playboy Mansion, but she'll be happy playing second fiddle on Kendra Wilkinson's wedding day.

"I told her a better be a bridesmaid," Madison said of her former Girls Next Door costar.

Wilkinson's engagement to Philadelphia Eagles receiver Hank Baskett was announced Thursday by her famous ex-boyfriend, Playboy founder Hugh Hefner. A ceremony is set for next June at the famed Playboy Mansion.

"I haven't met [Hank] but she's crazy about him," Madison told PEOPLE at the premiere of Repo! The Genetic Opera at the Planet Hollywood Resort and Casino in Las Vegas. "He's a really great influence on her and I'm so happy for her."

And Wilkinson isn't the only Hefner ex who's moved on. Madison admits that she's serious about her new boyfriend – Mindfreak star Criss Angel – who joined her at the movie premiere.

In fact, she said, "I'm in love with him."
