Nick & Jessica's House for Sale
The five-bedroom, 6,500 square-foot Mediterranean-style house, which includes an infinity pool, a screening room and a music studio, is being listed by Kay Cole of Sotheby's International for $3.75 million, a source close to Lachey says.
After the couple announced their split in November, Lachey, 32, remained at the house while Simpson, 25, moved into her parents' L.A. home.
Simpson, who filed for divorce on Dec. 16 after three years of marriage, has since moved into a new $3 million Beverly Hills home, which she purchased last month.
"She's happy to have a house that's hers," a source close to the pop star told PEOPLE last month. "This is the first time she's making her own decisions."
