Two more celebrities have joined Brad Pitt and Angelina Jolie in vowing to remain unwed until marriage equality is achieved.

Singer Jason Mraz told Us magazine that he won't be making fiance Tristan Prettyman his bride until gay marriage becomes 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.”

“The wedding would be nice for our family, our friends, our community – our moms especially – and so it puts us in the fight,” he added. “We can't get married until [gay] marriage is legal and equal. … I think giving people the right to marry will be a huge movement in civil rights.”

The 33-year-old crooner was spotted last week attending Elton John's concert to support gay rights group AFER.

Full House alum Jodie Sweetin, who recently became engaged to Morty Coyle, agreed.

“We are in no hurry as far as dates or anything like that,” she told People magazine. “We want to wait until there's equality for everybody to get married.”
