'Hills' Stars Laugh Off Spencer Pratt's New Cowboy Style

'It's really fun to make fun of him lately,' sister Stephanie Pratt says.

Heidi Montag expressed concern for husband Spencer Pratt's new cowboy hat in the trailer for the new "Hills" episodes. He's been seen all over Los Angeles rocking the hat, and he seems pretty comfortable in the Western gear — but his friends don't quite get it.

Kristin Cavallari just sort of laughed the fashion statement off in her devil-may-care style. And former bro Brody Jenner can't quite figure out what Spencer is up to now that he's in his wild, wild West phase of life.

"Every time I go to film or I'm filming with somebody else, I hear stories that Spencer's wearing cowboy hats all the time now and wearing charms, some kind of necklaces," he told MTV News. "I've heard a lot of things, but I haven't been able to see it myself."

Little sister Stephanie Pratt thinks the whole cowboy look is just odd. "It's really fun to make fun of him lately. ... I go over to their house, and I'm like, 'Spencer, stop going through Heidi's clothes.' It's really fun," she said. "He says the cowboy hat is, like, a gift from Dad and blah blah blah, but he's, like, getting really scary."

It seems Spencer is the only one who doesn't see what the big deal is. "Well, it was because my new father-in-law gave it to me, and he gave it to me with such a serious speech connected to it [about] how much it truly meant to him and his life and everything," Pratt explained. "For me, it wasn't really more a fashion statement — it was more something for my father-in-law."

To check out Spencer's cowboy style, tune in to "The Hills" every Tuesday at 10 p.m. ET on MTV.
