Dirty dancing: Rihanna and her friends let their hair down
It’s hard to believe Rihanna was planning a quiet night to celebrate her 22nd birthday.
But baseball star Matt Kemp, her rumoured new boyfriend, still caught her out with a raucous surprise party.
He even arranged for a 4ft tall stripper, Bridget The Midget, to give Rihanna a lapdance, as she sat laughing in a chair.

And even though she wasn’t expecting the bash, Rihanna soon got into the party spirit.
At one point Rihanna and a female guest were grinding away on the dance floor, making the most of the time off.
Luckily Rihanna was appropriately dressed for the occasion in a skintight nude dress with cut out panels and sparkly tiara.
And with the addition of a plastic tiara she was ready to party.
Kemp spent more than a month organising the event.
Witnesses said guests sang Happy Birthday to the R&B star and Kemp presented her with a birthday cake decorated with copies of her tattoos.
The Rude Boy singer was also presented with a pile of presents at the party, in Phoenix, Arizona.
After her bash, Rihanna headed to Germany to do promotional activities for her new album.
