In 2016, she played Sandy in the live Fox television production of Grease. Hough was one of the Million Dollar Dancers in the 2006 ABC game show called Show Me the Money. On November 27, 2007, Hough and her partner, three-time Indianapolis 500 champion Hélio Castroneves, became the winners of season five.
She left London that year, after having been "abused, mentally, physically, everything," she said, a situation that escalated "when I started hitting puberty, when I started becoming a woman and stopped being a little girl. I was told if I ever went back to the United States, three things were going to happen. Hough returned for season six with radio host/comedian Adam Carolla, but they were eliminated in week four.
They embarked on the sold out tour on May 25, 2014 in Park City, Kansas and ended it in Los Angeles on July 26, 2014.
Due to the success of ticket sales and several sold out venues before the tour had officially kicked off, several more shows were added to the tour schedule, which also sold out.
In June 2012, Hough told AOL's The Boot that her second album was "completely done" and that she was initially "really, really looking forward to the record." However, she also stated that, due to the underperforming lead single and having "a lot of momentum" in her film career, there are no plans to release Wildfire.
She does intend to resume focusing on her music career at some point, though: "I feel like when I have the time to focus on it, and when I feel like it is the right time, [I'll return to] my music," she said.
Following the success of the 2014 tour and high demand, the Houghs announced the return of "Move Live on Tour" in the summer of 2015.
Spanning from June 12, 2015 to August 8, 2015, the sold out tour visited over 40 cities throughout the U. and Canada, and visited larger venues than in the previous year.
The participants then took part in a two-mile run along Ventura Blvd, before finishing off with a dance-fitness class at Just Dance Los Angeles. She later signed with Universal Music Group Nashville's Mercury Nashville division.
On November 20, 2008, Hough told Ryan Seacrest on his radio show she would not be returning to Dancing with the Stars, for the foreseeable future, in order to further her music career.
On October 11, 2011, Hough returned to Dancing with the Stars and danced with her Footloose co-star Kenny Wormald twice, as well as her brother.
Hough returned to the show, although the pair was ultimately eliminated in the Semifinals Competition.
She appeared on the November 12 results show dancing the jive to "Great Balls of Fire" with her brother for the "Design-A-Dance" contest.
