JULIANNE FILLS TYRA BANKS' DANCING SHOES

Hough will host Dancing with the Stars following Tyra's exit after three seasons

HOOFER Julianne Hough is returning to her Dancing with the Stars roots — but this time as a co-host instead of as a toe-tapper — replacing Tyra Banks, who's departed under a cloud of bad ratings.

The 34-year-old hottie will co-host the celeb competition with former Fresh Prince of Bel-Air star Alfonso Ribeiro while her dancer brother, Derek, 37, will take a seat as a judge next to Carrie Ann Inaba and Bruno Tonioli, says a top industry source.
