Though the dashing Prince William celebrated his 16th birthday just two weeks ago, his pre-pubescent brother, Prince Harry, will be the one receiving a massive gift on Sunday. |

Harry's all-time favorite girl band, All Saints -- Sorry, Spice Girls, you're old news -- jumped at the chance to perform at this year's Prince's Trust Concert after receiving a personal invitation from the Royal 13-year-old. The hand-picked All Saints will join former Take That heartthrob Robbie Williams, Australian chart topper Natlalie Imbruglia, Scotland's Simple Minds and the Irish pop sensation Boyzone.

"All Saints is Prince Harry's favorite band and his favorite song is 'Bootie Call' [from the band's self-titled 1997 debut]," a spokeswoman for the group told JAMTV on Thursday. "They are very honored to play."

Mick Hucknall of Simply Red hopes to break his current promotional schedule to play a song or two for the concert, according to a spokeswoman for the redheaded crooner. A close friend of the late Princess Diana, Hucknall contributed to her benefit album and previously performed with George Michael and David Bowie at fundraising concerts organized by the princess. Hucknall has not assembled a backing band since the release of Blue earlier this year, so he will likely perform alone.

The annual benefit concert will take place at London's Hyde Park and all proceeds will benefit the Prince's Trust Charity. (Anni Layne)
