Here's something for “Gossip Girl” to talk about. Actress and singer Hilary Duff, who had a recurring guest role on the popular CW series last season, is engaged to Edmonton Oilers forward Mike Comrie. Publicist Nanci Ryder says the two were engaged last weekend while vacationing in Hawaii. She says in an e-mail distributed by the Oilers Friday that the two “are very excited to share this happy news”. The proposal comes during the National Hockey League's two-week break for the Olympics. The 22-year-old Duff and 29-year-old Comrie had been dating for over two years.
