Britney Spears reportedly hired female midgets to entertain her husband on his birthday.
The pop babe asked two little people to carry a cake to hubby Kevin Federline during his 28th birthday party at exclusive Las Vegas nightspot, Tao.
The following night the pair visited the same club, and Britney arranged for a Cher look-a-like to perform a duet of "I Got You Babe" with a midget Sonny Bono impersonator.
A source is quoted on website www.postchronicle.com as saying: "It was a special birthday indeed."
"Everyone found Britney's surprise really hilarious. Kevin and Britney and their friends were in fits."
As the pair partied, Britney was spotted sipping an alcoholic cocktail - casting doubt on speculation she is pregnant.
The sexy star - who has a five-month-old son, Sean Preston, with Federline - has been at the centre of pregnancy rumors since she was photographed sporting an apparent baby bump during a recent holiday in Hawaii.
