Scarlett Johansson learning from Sean Penn

Scarlett Johansson loves being with new beau Sean Penn because he’s so knowledgeable.

Sources say the actress has assured pals who worry he’s getting too serious too fast that she’s “not rushing into anything” after her painful breakup with hubby Ryan Reynolds.

“Scarlett says every day with Sean is an education equivalent to a college course he’s so worldly and knowledgeable,” a source said.

“She knows she married Ryan way too fast, but insists she’s a quick learner. Even though marriage seems to be on Sean’s mind and he’s pushing things a little fast, Scarlett’s doing her best to hold him off at the pass.”

Meanwhile, Scarlett has reportedly moved in to Sean’s $3.8 million Malibu home.

“Scarlett has essentially moved in over the last few weeks,” a source said.

“They just stay home whenever they can.”
