Fox Sports reporter Andrews -- who competed on the show in Season 10 -- will appear alongside longtime "DWTS" co-host Tom Bergeron in Season 18.

Burke-Charvet announced during the weekend she had been fired from the show after eight seasons as a co-host. Producers later confirmed the news, but didn't offer a reason for her dismissal.
