Stephanie Pratt isn't really feeling brother Spencer's latest accessory. As fans know by now, Spencer has been donning a cowboy hat lately — and it seems that's not the only Western garb that he's been rocking around "The Hills."

"His Amish hat?" Stephanie joked to MTV News. "The best part, though, is he's wearing cowboy boots with heels, so he clunks. You hear 'em. Even past the hats, now he wears crystals."

Stephanie says that she's not afraid to call her older brother out for suddenly becoming an urban cowboy. She also doesn't really buy that he's wearing all of this as some sort of tribute to his father-in-law Cowboy Bill, either. "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 explained. "He says the cowboy hat is, like, a gift from dad and blah blah blah, but he's, like, getting really scary."

However, Spencer has assured MTV News that he is indeed wearing the gear on the show because Cowboy Bill asked him to. "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. "He even kind of hinted at how cool it would be to see it on the show for all his cowboy friends back in Colorado."

Check out Spencer's cowboy style for yourself when new episodes of "The Hills" premiere Tuesday, September 29, at 10 p.m. ET on MTV.
