Singer Ashlee Simpson has purchased her first home - and she's sharing it with two of the girls who appeared as her friends in her video for 'La La'. The 20-year-old brunette recently moved into the pad in Studio City, California. She tells MTV, "It's so much fun. We've been decorating it and everything; it's kinda got like a retro vibe. Hopefully when I'm home next month, I'll be able to do some work around the house. "I am the messiest in the house, by far. My girlfriends are messy, too, but I win. I take the cake!"
