Britney Spears' Birthday Surprise for Her Husband

Some stars are well known for their questionable sense of humor. And in that department, from the merry world of Britney and her husband, Kev, comes another amusing story that resembles quite a lot one of the weaker episodes of Punk'd.

After drastically cutting down her husband's allowance, the pop diva came up recently with a cute little joke.
Britney made her husband believe that she had hired Cher to perform for him. She told Kevin that she has booked the "I Got You Babe" star as a present for his birthday, which the couple celebrated in Las Vegas.

During the after-hours party at Tao, Britney presented Federline a suspiciously chubby - looking woman that was impersonating Cher. The look-alike made her entrance singing along to "If I Could Turn Back Time". Apparently, it took a while before Kevin realized that he was being fooled.

One of the witnesses present at the location said: "It was a special birthday indeed. Everyone found Britney's surprise really hilarious. Kevin and Britney and their friends were in fits. Kevin finished the night off by dancing to his wife's I'm A Slave 4 U and then hitting the DJ booth to play songs from his new album."
