Tunstall is now engaged to drummer Luke Bullen, who proposed on Christmas day, according to People magazine. "Being an opportunist, I obviously said yes," said the 32-year-old singer.
Tunstall and Bullen plan to marry in 2008. The singer was nominated for a Grammy Award for her 2007 song Black Horse and the Cherry Tree, and also earned a BRIT award for Best British Female Solo Artist in 2006.
