Julianne Hough to judge 'Dancing with the Stars'

Dancer Julianne Hough is to return to 'Dancing with the Stars' as a judge.

The 26-year-old professional dancer will allegedly become a fourth judge, alongside returning stars Carrie Ann Inaba, Len Goodman and Bruno Tonioli, reported TMZ online.

Both Hough and the producers of the show are "in negotiations".

Meanwhile, last month her brother Derek Hough revealed that his future on the show was uncertain.

ABC premieres the new season of 'Dancing with the Stars' this autumn.
