Pop star ASHLEE SIMPSON was hesitant about buying her first home - because she's lived like a slob in rented accommodations.

The PIECES OF ME singer, younger sister of JESSICA SIMPSON, recently purchased a home in Studio City, California, which she's sharing with two pals, but she admits she thought long and hard before making the commitment.

She says, "I wouldn't have bought the house without going to my parents and being like, 'Okay, do you think I'm ready?' They were like, 'Yeah, you can do it, you just can't live how you have been in your apartment.'

"I was living like a fraternity boy. It was bad. There were like potato chips under the couch and my parents were, 'You have to be clean!'"
