Want to be a backup singer for Alicia Keys? The R&B star is inviting female singers who are 21 - 30 years old to "audition" via MySpace.

Hopefuls have until May 5 to submit a video, 30 seconds or longer, of themselves singing acapella to Keys' MySpace site; according to a release. Ideal candidates "must be physically fit and able to dance."

There's no word yet on what portion of the "No One" singer's tour the backup singer would take part in; however, current dates run now through June 18, with more on the way. As previously reported, Keys has plans to tour through 2009. In the meantime, she's been mulling a new effort.

"At this point I'm trying to find the space to continue to record as I'm on tour," Keys told Billboard.com last month. "That's always a bit of a challenge for me 'cause it takes so much out of me to tour. But there's always that urge to stay creative and write on that more personal side. So the main goal now is to continue to find that quiet space somewhere in the madness."
