Scarlett Johansson is pregnant?

Scarlett Johansson isn’t with child!

The actress who’s currently dating actor Sean Penn has been forced to deny she’s pregnant with her first child.

Scarlett fueled pregnancy speculation after she was photographed with a fuller figure during a jog with Sean.

The star, 26, appeared to have a small bump beneath her tight grey vest and black Lycra leggings.

But Johansson insists she’s not expecting!

“Scarlett is not pregnant. She’s outside running and it’s simply the placement of her shirt that is misleading,” her rep said.

“She’s been training for The Avengers for over four months and is in the best shape of her life.”

Meanwhile, Scarlett has reportedly moved in to Sean Penn’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.”

Johansson and Ryan Reynolds, 34, split in December after two years of marriage. In August of 2009, Robin Wright, 44, filed for divorce from Penn. The couple had been married 13 years.

Scarlett and Sean were first linked last month.

“Scarlett first reached to Sean when she was planning to visit Haiti with Oxfam,” a source told Us Weekly magazine.

“She knew Sean was living there in a tent and turned to him for advice.

“Scarlett’s smitten with him.”
