Scarlettt Johansson living with Sean Penn?

Scarlettt Johansson has been moving her clothes into Sean Penn‘s house in Malibu, California.

“She’s at his house most nights and has been accepted by his teenage sons,” a source said.

“Things have moved at a fast pace and both feel they have found their perfect match.”

Sean and Scarlett were seen engrossed in an “intense” makeout session at Saturday’s White House Correspondents Dinner in Washington, D.C.

“It happened right as the main course of the dinner was being put on the table,” a source told Us Weekly magazine.

“Scarlett was pawing at Sean, holding on to his hip while he was smoking. She gave him a short kiss.

“But then they took a walk some 30 feet away, broke off from the group and kissed some more.

“Around 1 a.m. Sean showed up and he and Scarlett were immediately side by side for the rest of the night.

“When they were walking out the door, Sean stopped her, took off his jacket and put it on her shoulders, saying, ‘It’s cold out there.’ They then grabbed hands and walked out before 3 a.m.”
