People.com said the decision was revealed Monday on the network's "Good Morning America" program.
"Dancing" co-host Samantha Harris announced last January she was leaving the popular show.
Burke is expected to replace her and work alongside co-host Tom Bergeron when the series returns for its 10th season March 22.
Burke previously served as host of the reality series "Wild On," "Rock Star: INXS" and "Rock Star: Supernova."
"She'll be able to talk to the couples backstage with the perspective of having been there herself," People.com quoted Bergeron as saying when he made the announcement on "GMA" about her hiring.
