ST. LOUIS - St. Louis rapper Nelly is used to having DJs play his music on the radio. Now, he's the one spinning tunes.

Program director Mickey Johnson says the rapper has joined St. Louis urban station Hot 104.1 (WHHL-FM) as the afternoon drive-time host. He is filling in on the 3-7 p.m. shift for Staci Static, who is on maternity leave.

Station executives expect Nelly's on-air stint to last for about a month.

Johnson says the station wanted someone with star power. In addition to playing music, Nelly will conduct interviews.
