Britney Spears doesn't turn 32 until Monday, Dec. 2, but the pop princess received an early birthday surprise from Sophia Grace and Rosie on the Friday, Nov. 22, episode of The Ellen DeGeneres Show. The British BFFs visited the "Perfume" singer at her rehearsal studio, where they received a dance lesson from choreographers Antony Ginandar and Ashley Evans.
As the two learned the moves to "Work Bitch," Spears snuck up on them. "Your dresses are beautiful," she said, admiring their beloved tutus. "Are you doing my choreography?"
The pals chatted about possible Christmas presents giving Spears an early present. "We're almost going home to England, " Sophia Grace said, "so before we do, we've got a massive surprise for you."
Spears—who introduced the girls to her dancers as "my two new best friends"—held hands with Sophia Grace and Rosie as they led her to a party set-up. Naturally, the theme was Disney Princess.
"This is spectacular! Oh my goodness!" said Spears, a former Mousketeer. "I don't know what to say! I'm speechless."
As they put on party hats, Sophia Grace asked the "Alien" singer to share her birthday wish. Spears said she wants to take "four vacations a year," which seems reasonable given that she signed a two-year residency with Planet Hollywood Las Vegas.
Rosie, meanwhile, said hers would be "to have all best friends and everyone be happy." So precious!
Before Sophia Grace and Rosie headed home, they gave Spears a final gift: a tiara with an attached mic and a pink tutu. "Thank you guys!" Spears said. "Now my show will be perfect."
