Derek Hough still thinks "very highly" of Kate Hudson's ex-fiancé Matt Bellamy.
The 'Dancing With the Stars' performer reportedly waited until the 35-year-old actress - who recently confirmed she'd split from the Muse rocker - was single before hooking up with her after they formed a close bond when she took dancing lessons from him last year.
A source said: "Derek thought very highly of Matt, and still does. He did not try to hook up with Kate while they were together. He's a good guy.
"Derek thinks Kate is gorgeous. Ever since the dance lessons, he knew they had chemistry."
The 29-year-old professional dancer and the blonde beauty - who are said to have grown close after the 'Something Borrowed' star admitted her engagement was in trouble - surprised everyone when they "acted like a couple" at a party in Los Angeles on December 5.
But an insider told Us Weekly magazine: "As Kate told Derek about her problems with Matt, they grew closer and closer. Derek knew the relationship was over, so he didn't think twice about hooking up with Kate."
The duo were also seen kissing at The Nice Guy restaurant recently.
An eyewitness said: "She sat on Derek's lap. They were all over each other, making out in their own little world."
Meanwhile, Kate and Matt, who have three-year-old son Bingham, are still on good terms, and another source said: "Kate and Matt will share custody of their son. Bingham will visit his dad on the road."
The actress also has 10-year-old son Ryder with her ex-husband Chris Robinson, who she separated from in 2006.
