Jason Mraz and Tristan PrettymanJason Mraz may be engaged to fellow singer Tristan Prettyman, but don't expect the couple to walk down the aisle until gay marriage is legal.

"We both feel that in our engagement, we have a union that's really special and can't be broken. It's a sacred bond," Mraz told Us Weekly. "The wedding would be nice for our family, our friends, our community -- our moms especially -- and so it puts us in the fight."

The singers plan to wait to get married until it's allowed for everyone.

"We can't get married until [gay] marriage is legal and equal," the 'I'm Yours' singer continued. "I think giving people the right to marry will be a huge movement in civil rights."

So until then, the couple is enjoying their newly-engaged status. Mraz, 33, proposed to Prettyman, 28, on Christmas Eve, and the engagement has changed the singer's outlook on life.
