Actress Roma Downey and reality-show producer Mark Burnett are engaged, a publicist for the pair said Monday. Burnett proposed to Downey during a Thanksgiving trip to Mexico, publicist Jim Dowd said. Both are 46.

"They have never been happier," Dowd said. "They are enjoying this exciting time with their children and their families."

The couple, who started dating in 2004, plan to marry next year.

"I have found my angel," Burnett said in a statement.

Both have children from previous marriages. Burnett has two sons, ages 13 and 9, and Downey has a 10-year-old daughter.

Downey starred in the TV show "Touched by an Angel" from 1994 to 2003. Burnett is the producer of reality shows including "Survivor" and "The Apprentice."
