'Hills' Season Premiere: Heidi Montag Reveals Cosmetic Makeover To Her Parents

From the cover of People magazine to a much-publicized sit-down on "Good Morning America," Heidi Montag has made the rounds flaunting her brand-new body, a result of a staggering 10 plastic surgery procedures. But on Tuesday's final season premiere episode of "The Hills," the 23-year-old may have faced her harshest critics: her parents.

The episode opened with Heidi's sister-in-law, Stephanie Pratt, and Lo Bosworth discussing Stephanie's recent DUI and Super Bowl weekend plans in Miami, but the conversation quickly turned toward rumors of Heidi's makeover.

"There's been some talk about Heidi and a new face," Lo divulged. "This is all hearsay: eyebrow lift, ears pinned back, nose job, chin job, boob job, butt job." Having not seen Heidi or brother Spencer in months, Stephanie could only sit, mouth gaping in awe and confusion over the prospect of a butt job.

At home, Heidi was busy packing her bags for a trip to Crested Butte, Colorado, to see her parents. Though husband Spencer warned her that the trip was a mistake, Heidi insisted on going because she hadn't seen her family since their wedding — before she went under the knife. With sister Holly in tow, Heidi arrived in Colorado to a lukewarm and slightly bewildered reception.

"It's very weird and awkward," began mom Darlene, investigating her daughter's new face. "You risked your life to do the things that you did. You had an elective surgery that was completely unnecessary. I feel like when you left home, you had more confidence and self-esteem than anyone I had ever met."

When Heidi pointedly asked her mom if she liked her new look, Darlene couldn't give her the answer she'd hoped for. "How do I say that I thought you were more beautiful before?" Darlene asked. "But, yes. I thought you were much more beautiful before. I'm hoping some of this will fade and go away."

This elicited a contorted sob from Heidi — the best she could do with her sore, fragile face. The rest of Heidi's trip was seemingly spent defending her plastic surgery to her worried family.

Meanwhile in Miami, Stephanie and Lo frolicked on the beach and partied in the clubs with Audrina Patridge, Kristin Cavallari, Brody Jenner, Sleazy T and Frankie. Brody paid extra attention to Audrina, eliciting a twinge of jealousy from the now-single Kristin, who ended things with Justin Bobby.

"For once the guy she wants back doesn't want her. He wants me," Audrina mused.

A couple of hard-partying, late nights later, the girls began to worry about Kristin's erratic lifestyle. Having been awakened in the middle of the afternoon to catch a flight home, Kristin overheard the girls gossiping about her and confronted them.

"People are saying things about you," Lo replied. "Everyone is saying that you're doing drugs." Kristin flatly denied the rumors, turning the attack back on Stephanie and her alcohol issues, before leaving the hotel room in a huff.

But not to worry, Kristin did make it onto a plane headed back to the Hills.
