Actress Shannon Elizabeth has laughed off reports she is engaged to her former Dancing With The Stars partner Derek Hough.The couple met when the American Pie star was paired up with the hunky dancer to compete in the 2008 series of the U.S. talent competition, in which they came in sixth place.America's Star magazine reported last month that their relationship was going so well, Hough had proposed to Elizabeth - but she turned him down. But the 34-year-old claims there is no truth to the speculation, insisting they are happy as boyfriend and girlfriend.She tells People.com, "There's this whole weird rumour going around. One of them says that he proposed and I said no, and the other says he proposed and I said yes, and we're getting married. Neither one is true."Meanwhile, Elizabeth is preparing herself for the forthcoming seventh season of the reality TV contest - when 23-year-old Hough will be paired up with a new teammate.She jokes: "(Hough is) going to get his new partner in a couple weeks. We have no clue who the co-star's going to be. I'm hoping... (it is someone) who's like 70, 80 years old."
