Kate Hudson came to watch her pal tango at Monday's Dancing with the Stars
The 35-year-old actress was able to slip in and out of the Los Angeles soundstage without many people knowing, especially the press, who were assembled backstage.
Though she and Hough, 29, have been dogged by rumors that they are dating, a source close to the pro hoofer told PEOPLE the two are “just good friends.”
Hough is bi-coastal these days, because he’s splitting time between DWTS – where he and Liukin were the first couple this season to earn three 10s during Monday’s performance – and New York’s Radio City Music Hall, where he’s starring in the Spring Spectacular.
Unlike Hudson, Moore was caught on camera cheering for her daughter Rumer Willis, who together with Val Chermkovskiy earned a 35 for her waltz.
