Rihanna celebrated her 22nd birthday over the weekend with a shindig put on by Los Angeles Dodger Matt Kemp in Phoenix where the center fielder is at spring training.

Although her good pal Katy Perry couldn’t make it Saturday – “Love you girl, wish I could be there,” she Tweeted – Rihanna flew out a bunch of her pals for the bash, highlighted by the singer getting a dance from a stripper.

“It was a female little person,” says a source of the strip tease. “She thought it was funny!”

Rihanna, who wore a beige mini-dress, was serenaded with “Happy Birthday” as Kemp, 25, brought out a cake decorated with the singer’s tattoos, reports E! News. The guests also sipped champagne and noshed on Sprinkles cupcakes and appetizers prepared by a Jamaican chef. Tiki torches added to the décor.
