Spencer Pratt: Heidi Wasn't Happy After Surgery

Heidi Montag got 10 plastic surgery procedures in one day -- and despite claims that she loves the results, Spencer Pratt tells Us she was originally not happy.

"She came out of the hospital and the only thing she was saying was that the doctor better hide," Pratt, 26, told UsMagazine.com at Pure nightclub inside Caesars Palace in Las Vegas Saturday night.

"She wasn't happy," Pratt continued.

The aspiring pop star says she had "no idea" how painful all the procedures would be.

"The worst pain was actually my ears. I didn't know that was the most painful process and feature," she told Us of having her ears pinned back.

Still, Montag, 23, wants a third boob job.

"I didn't get them as big as I originally wanted," she told Us. Added Pratt, "She doesn't stop talking about it."

So how did the couple spend Valentine's Day?

"My Valentine's present to Spencer is going shooting at the gun range," Montag told Us.
