Real estate records reveal Duff bought the 9,277 square-foot house in Toluca Lake, Calif., in March 2004 for $3.5 million. Mark Wahlberg, a.k.a. Marky Mark, also recently re-listed his Beverly Hills estate with a $2 million price cut. Wahlberg originally listed the property in 2008 for $15.9 million. The 1.41-acre home is now listed for $13.9 million. The executive producer of Entourage purchased the mansion in 2001 for just $5 million, later remodeling it.
