Millions of fans spent the past decade feverishly devouring "Harry Potter" books and movies, even as they longed for answers to the many lingering questions: What is Harry's fate? Who will live and who dies? What will happen between Ron and Hermione? Now, with the final two "Potter" films on their way, one of the series' stars, Tom Felton, provided some insight at the 2010 MTV Movie Awards about another pressing question: What will it be like to say goodbye?

"I had my last day shooting three days ago," revealed [article id="1639140"]Felton, known onscreen as Draco Malfoy[/article]. "So the blond hair is gone."

Before heading into the Gibson Amphitheatre to collect his award for Best Villain, Felton dropped an even bigger bombshell. His girlfriend, "Potter" stunt assistant Jade Olivia, will have an acting cameo in "Harry Potter and the Deathly Hallows."

"This is an exclusive for you -- she is, yes," Felton told MTV News. "The producers came to me about six months ago, and I said, 'OK, I'll ask her.' She was at first reluctant, but I pulled her arm and twisted it. She was filming with me for three days at King's Cross [railway station in the U.K.]; we were very excited."

Olivia and Felton appear alongside Daniel Radcliffe, Emma Watson, Rupert Grint and other castmembers in an epilogue that depicts the "Potter" stars after the "Deathly Hallows" films have concluded. "She plays my wife, Astoria Malfoy; we have a kid together," Felton said. "It was all very rush, rush. So yeah, we were married for three days. It was fun."

"It gave me a chance to see what she's going to look like in 19 years," Felton joked. "And if that's what she looks like, I'm doing pretty well for myself," he laughed, commenting on the makeup work. "But I look terrible. The years have not been kind to me in the slightest. But what can I do? I've gotta just roll with it."

"It's amazing," he said of the epilogue. "I don't want to drop too many hints, but Rupert, Daniel, Emma, they all look fantastic. There's lots to look forward to."

Fans, of course, can look forward to the unveiling of "Deathly Hallows" beginning in November. Part two of the split-for-cinema sequel hits theaters in July 2011. But as for Felton and his gal-pal, the anticipation of the films paled in comparison to the thrill of attending the 2010 MTV Movie Awards.

"I've never been here," Felton explained. "This is my first American awards show, period. And MTV is my life, man. I grew up with this stuff. So to be here is a massive honor, let alone to be nominated."

"It's a sad thing," Felton said of saying goodbye to the "

"Potter" franchise. "But it was also exciting, and what a way to end it -- to come and celebrate it here."
