It's like they never left!

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."
