Actress Amber Riley and her professional partner Derek Hough were declared the winners of Season 17 of "Dancing with the Stars" in Los Angeles Tuesday night. "Oh, my God! I did this competition because I didn't know if I could do it and anything that scares me, I want to do. So I want to let women of all sizes out there know, you can do whatever you put your mind to," the 27-year-old "Glee" star said upon learning her fate. "It doesn't matter what size you are, what color you are, you can do whatever, whatever, whatever you put your mind to." Singer-actor Corbin Bleu and reality TV personality Jack Osbourne came in second and third place respectively with their partners. Season 18 of "DWTS" is to premiere on ABC in March. The cast has not yet been announced.
