REESE WITHERSPOON has finally agreed to marry actor JAKE GYLLENHAAL at Christmas, according to a new report.

Brokeback Mountain star Gyllenhaal has reportedly told friends he plans to wed Witherspoon, 32, in December (08) after he finishes filming his forthcoming adventure movie, Prince of Persia: The Sands of Time.

A source on the movie's Morocco set tells British newspaper The Mail on Sunday, "Jake is telling everyone they are getting married at Christmas.

"He told me he had proposed several times but she kept telling him she wanted to give their relationship more time.

"When he asked her again a couple of weeks ago, she finally said yes."

The couple met in 2006 on the set of their thriller Rendition.
