Tyra Banks Named New Host of 'Dancing With The Stars'!

Tyra Banks is moving from judging the catwalk to hosting in the ballroom ... the OG top model is taking over MC duties for "Dancing With the Stars."

Just a day after ABC dropped Tom Bergeron and Erin Andrews leading into season 29, TMZ has learned the former supermodel is strutting her way into that role.

In addition to smizing in front of the camera, Tyra will also be an Executive Producer of the show. We've learned she was in talks with the network long before ABC cut ties with Tom and Erin.

On Monday, Tom announced the show would be continuing without him, and said his 15 years hosting were the "most unexpected gift of my career." ABC and BBC released their own statement about Tom and Erin's departures ... saying the show is embarking "on a new creative direction."

Sources close to Tom tell TMZ the news came as quite a shock to him, and he was only informed of his departure this week.

The pair had been co-hosting together since 2010, after Erin was a contestant on the show -- but now, as Daily Mail first reported, the "America's Next Top Model" creator will be stepping into that glittery, disco-balled arena.
