Lauren Conrad, Kim Kardashian Join 'America's Next Top Model'

Reality-TV stars are signed on for one episode each of the show, which returns in September.

Just when you thought Lauren Conrad was done with reality TV — and on hiatus from her fashion career, for that matter — she's making her way back to both arenas as a guest judge on "America's Next Top Model."

In addition to Conrad, Kim Kardashian — star of her own reality show, "Keeping Up With the Kardashians" — will also be making a cameo for the 13th cycle of the show, E! Online reports. Both LC and Kardashian are signed on for one episode each. LC will be on the September 16 episode, with Kardashian making her appearance October 21.

Conrad recently told MTV News that she wouldn't rule out returning to TV, but she did warn that when or if she did, she'd want to do it in a hosting capacity. "I wouldn't do a show like 'The Hills,' " she said in June. "Nothing with my personal life, but possibly something hosting. I think I have a little bit of time to figure out what I'm going to do next."

Now that we'll be seeing LC on TV again, is there any chance we can catch her on the upcoming season of "The Hills," starting in September? "I'm not planning on it," she said. "I'm happy with the time I walked away, and I think that from now on, they're going to pick it up and do a great show. But I think that my time on it is done."
