If the guy you mean is Cedric Diggory from the Harry Potter movies, then I can say with not-complete confidence that he is in fact single, as his Myspace page describes him so and his last login to this page was Friday. So unless he didn't feel like changing it then, is deceptive or simply doesn't think it anyone's business to know he has a g/f, my research is accurate. Please feel free to see it yourself if you like .

-and this info is at the very bottom.
Also his birthday is in 12 days(depending on when you get this--its May 13) so, a nice opening might be to send him a gift. If you are so inclined. His c/o address can be found on his Veritaserum.com page. Or maybe my impression of the tone of your question was off. If not, I'd suggest something making something elegant, as made gifts and ones that look priceless both make impressions on Taureans.
