ABC has made it official: Fox Sports anchor Erin Andrews is Tom Bergeron’s new partner as host of “Dancing With the Stars.”

ABC also confirmed that the dancing competition will have a new musical director when its latest edition bows March 17.

Ray Chew, who has worked on “American Idol,” numerous editions of the BET Awards and last year’s Emmycast, will replace longtime music maestro Harold Wheeler. The show will make other changes in the lineup of musicians and singers who perform the live accompaniment.

The shuffles at “DWTS” come as the show has continued to see its audience dwindle. The show was slimmed down from two episodes a week to one last fall and will continue with that pattern for its spring edition.

“DWTS” will unveil the celeb participants for its 18th edition March 4 on “Good Morning America.”

Andrews replaces Brooke Burke-Charvet, who spent seven seasons on “DWTS.” She was let go late Friday — and announced her dismissal via Twitter.

Andrews is a former “DWTS” competitor who spent eight years ABC sibling ESPN before shifting to Fox Sports in 2012.
