Katy Perry threw her friend and stylist, Johnny Wujek a rollerskating birthday party at MoonLight Rollerway in Glendale, California Saturday night (July 14th).

Wujek, who will serve as a mentor on the upcoming season of America’s Next Top Model, was feted by the likes of Amber Heard, Rachel Bilson, and Hayden Christensen.

Perry made sure partygoers kept to a 90s theme, and brought along a pink backpack full of beanie babies to toss at friends in the rink, according to the New York Post.  ”Bringing beanie babies back,” she tweeted Saturday night, wearing a floral tank top, denim cut-offs and floral bike shorts underneath.

Perry’s divorce from Russell Brand was finalized yesterday, as photos of Brand and a mystery woman surfaced from Sunday (July 15th).
