Heidi Montag is ready to marry Spencer Pratt–but only if he pops the question with a huge ring.

Last night Hollyscoop caught up with Speidi at the Pepsi 500 running wide open event in Hollywood, where the couple talked about Heidi’s new single, the VMA’s and their upcoming wedding plans.

So are they tying the knot anytime soon? “Hopefully soon,” said Spencer. “We’re tying to get things moving here,” he added. “Ya I need a ring soon,” Heidi said, to which Spencer joked, “We can go to the pawn shop.”

In Spencer’s words, since “Miss Montag wants a ring THAT big,” it looks like the wedding plans are going to put on hold for now. Check out our exclusive video with Heidi and Spencer below…
