Heidi: I've Had "Ups and Downs" With My Body

Reunited spouses Heidi Montag and Spencer Pratt packed on the PDA in Las Vegas on Saturday, where Montag, 24, hosted Pure nightclub's Halloween Haunt. Pratt, 26, dressed as a Close-Encounters-style alien; Montag skipped a costume, but showed off her surgically-enhanced curves in a gold mini-dress.

"I'm Heidi Montag for Halloween," she told reporters on the red carpet. "I designed my own dress."

How does Montag feel about her body (she famously had 10 procedures done in one day) these days? "Um, ups and downs!" she said. "I'm good. I'm just trying to focus on other things, not focus so much on my body."

A lot has happened since then. The Hills, the MTV reality show that made them stars, aired its final episode. And over the summer, the pair (who married in April 2009) separated, filed for divorce and then reunited.

Montag gushed on the red carpet that, this time around, she's "enjoying our relationship. I had so much going on [before, I didn't have a chance to enjoy being a newlywed."

One thing that's definitely real: Montag's sad isolation from most of her friends and family. Her mom Darlene Egelhoff hasn't seen her daughter in nine months, and is now working as a maid in Crested Butte, Colo. to make ends meet.

Egelhoff -- who loudly objected to Heidi's surgery and her husband Pratt -- admitted to Inside Edition that it's awkward when folks now recognize her from The Hills.

"That's very humbling for me and I very much appreciate that experience because I don’t ever want to get full of myself and think I’m too good to do anything."

Heidi & Spencer Pratt's Pure Halloween Party

Spending the holiday in Sin City, Heidi Montag and Spencer Pratt were side-by-side at Pure nightclub inside Caesars Palace Hotel in Las Vegas on Saturday night (October 30).

The attention-loving pair shared smooches with Spencer also making time to play around with a stuffed doll while hosting a Halloween bash at the popular nightspot.

During their time in Vegas, Heidi chatted with Doug Elfman of the Las Vegas Review-Journal about being back together with Pratt.

She said, "Fortunately, we are together. So it's been a long summer, and we are together, and I'm so excited to be in Vegas together and to have our friends there."

Continuing on, Heidi gushed, "I'm definitely feeling the best I've ever felt."
