Lauren Conrad dropped by The Ellen DeGeneres Show Monday to talk about her reality TV hit The Hills, which returns March 24, as well as moving into her new house and the launch of her clothing line. Some excerpts ...

On moving in: "[MTV] filmed us moving in. There were three girls (LC, Lo and Audrina). We had a lot of stuff. It was raining the whole weekend. We had like 15 crew members with cameras. It was madness... We thought the house was haunted. It was built in 1922â€"it was an old house. We felt it was kinda creepy. We were probably freaking ourselves out but we were convinced it was haunted."

On the popularity of The Hills: "I usually ask people when I meet them, what specifically they like about it. Mostly what I hear is that it's very relatable. The point of the show is that it doesn't matter who you are or what your situation is, everyone goes through the same things."

On her new clothing line: "It's what I always wanted to do. Growing up, I always wanted to be a fashion designer. I've been going to school for product development for about two years, and I finally launched the clothing line in stores this month!"

On Heidi Montag: "There is no relationship ... It's one of the most common things I get asked about ... We were friends, then we weren't, and it was really sad, but we've moved on, and the only time I talk about it is when people ask me."
