Scarlett Johansson: Has she already moved in with Sean Penn?

Since she formalized her relationship with Sean Penn by arriving in his company at Reese Witherspoon’s marriage last month, Scarlett Johansson wants to change things quickly.

The 26-year-old actress has moved in Penn’s $ 3.8 million residence located in Malibu, a source tells Us Weekly.

Johansson lived temporarily in a hotel in West Hollywood. She went to live with Penn, 50, “in recent weeks,” the informant says.

Having been spotted in Mexico, the couple prefers to “just stay home” as soon as they gets the chance, the source says. The two lovebirds love to eat at home and spend time with Penn’s children, born of his marriage to Robin Wright.

The actress and her husband Ryan Reynolds were divorced in December.
