The country singer is set to marry musician boyfriend Cactus Moser, who popped the question on Christmas Eve

Third time’s the charm?

Country music star Wynonna Judd is engaged to musician boyfriend Cactus Moser after he popped the question on Christmas Eve, PEOPLE has learned exclusively. The couple, who currently tour as Wynonna and the Big Noise, have been dating since late 2009.

The engagement is the latest chapter in a happy comeback for Judd, 47.

After suffering two health scares in March of 2010, and surviving a head-on car collision four months later, Judd turned her life around by losing 55 lbs. and reuniting with her mother, Naomi, for the first Judds tour in 10 years.

“I feel more alive,” she told PEOPLE last year.

This will be the third marriage for Judd. She divorced her second husband, D.R. Roach, after four years in 2007. In 1998, she split from Nashville businessman Arch Kelly III, with whom she had two children, Elijah, now 17, and Grace, 15.
