Eagle-eyed readers of Billboard's charts will surely have cocked eyebrows when they come across hip-hop track "I'm a Flirt." The song has been recorded by both Bow Wow and R. Kelly. Bow Wow's version features Kelly, who co-penned the track, while Kelly's version subs out Bow Wow for T.I. and T-Pain.

Due to the similar characteristics of each song, the plays for both versions will be totaled under one chart listing. This week, it debuts at No. 90 on the Billboard Hot 100 with the attribution Bow Wow or R. Kelly (featuring T.I. & T-Pain). It also climbs to a new peak of No. 15 in its sixth week on Hot R&B/Hip-Hop Songs.

"I'm a Flirt" first appeared on Bow Wow's Columbia/Sony Music album "The Price of Fame" as a hidden bonus track. iTunes shoppers, though, can purchase the track as a single, as Columbia has download rights -- but not the singles rights to promote it to radio.

Kelly, meanwhile, will include his version of the song on his as-yet-untitled new album, due May 29 via Jive.
