Just as he's reached the top of the album charts for the first time, Kid Rock has made a major change at the top of his business operations.

Rock's manager, Detroit-based Ed "Punch" Andrews, who also handles Bob Seger, has resigned after seven years of working with the Michigan rocker. Sources tell Billboard.com that Andrews has decided to retire after shepherding Rock's latest album, "Rock N Roll Jesus," to release last week.

"Rock N Roll Jesus" is Rock's first No. 1 album on The Billboard 200, selling just over 170,000 copies, according to Nielsen SoundScan.

Rock has reportedly replaced Andrews with Nashville-based Vector Management, which handles Bon Jovi, Lynyrd Skynyrd and others.

Neither Rock, who was performing in Nashville, nor Andrews could be reached for comment. It's unknown whether Andrews will continue working with Seger, whom he's handled since the late '60s.

Rock is in the midst of a theater tour to promote "Rock N Roll" Jesus." He also has TV appearances slated for "Ellen" on Oct. 25, ABC's "Jimmy Kimmel Live! on Oct. 26, the American Music Awards on Nov. 22 and on Larry the Cable Guy's VH1 Christmas special in December.

"Amen," the second single from "Rock N Roll Jesus," will ship to radio later this month, according to Rock's web site.
