Brad Pitt and Angelina Jolie announced Friday that they're engaged, despite the couple's vow not to marry until gay couples can legally join them.

Pitt first made the declaration in a 2006 Esquire interview.

“Angie and I will consider tying the knot when everyone else in the country who wants to be married is legally able,” the 48-year-old actor said.

The couple has since reiterated the pledge and given generously to the cause of marriage equality.

In December, Pitt told Ellen DeGeneres: “I've said that we would not be getting married until everyone in this country had the right to get married.”

In recent interviews, however, the couple has said that their six children have been pressuring them to marry.

Response has been mixed.

Equality California (EQCA), the state's largest gay rights advocate, supported the couple's decision.

“Marriage is something that says 'we're a family' in a way that nothing else can,” Rebekah Orr, communications director for EQCA, told TMZ.com. “No one has to deny that for themselves or their family to prove they are an ally and supporter of equality.”

GLAAD congratulated the couple on their engagement: “We congratulate them on their engagement and thank them for continuing to speak out about the inequality that so many gay and lesbian couples face today. No loving and committed couple should be denied the happiness, joy, and legal protections that come with marriage.”

But Brian Moylan, a staff reported with Hollywood.com, called the reversal a disappointment.

“I'm sorry, Brangelina, but real fighters for civil rights don't buckle under pressure when it gets hard,” Moylan said, then added: “If they're going to break their pledge and get married, the least they can do is hit their friends up for donations for marriage equality at the ceremony.”

“Leading by example is what gay and lesbian Americans really need, but since they're failed at that, we'll at least take their money.”
