Selena Gomez – who is dating Justin Bieber – splashed out on the 4,650 sq ft estate in Tarzana, Los Angeles, which Jonah Hill paid $2.175 million for in September 2011.
Although the property also features his and hers closets, it is unlikely Justin, 18, will be moving in as Selena recently revealed she is in no rush to settle down.
She said, "I'm lucky. It's really fun. [But] I'm 20. I don't take anything in my personal life too seriously. I have great friends and a solid group of people I love. I feel like everything else will come organically.
"Marriage and all that other stuff I think will happen once I feel accomplished in every other aspect of my life."
Before splashing out on her new palatial pad, Selena had been happy to remain living with her parents but acknowledged it could be time to move out.She said, "I have a small condo on top of my parents' house. I'm a little behind!"
