Los Angeles, Oct 6 (IANS): Actress Scarlett Johansson is said to be hurt after her ex-husband Ryan Reynolds married actress Blake Lively so soon after their divorce.

The actress, whose divorce from Reynolds, her husband of four years, was finalised in 2011, is said to be convinced he cheated on her with Lively while they were still married.

"Even though there is no evidence behind it, Scarlett has convinced herself that Ryan cheated on her with Blake," a source told the National Enquirer, reports contactmusic.com.

"She's incredibly bitter about it. In a way, Scarlett feels like Blake actually stole Ryan from her, because it was when he started shooting 'Green Lantern' with Blake in 2010 that everything fell apart," the source added.

Johansson was shocked to discover the couple had thrown a secret wedding reception in South Carolina Sep 9.

"Ryan and Blake's wedding has brought back a lot of pain for Scarlett. She's sure that Blake deliberately seduced Ryan, even though she knew he was attached at the time," said an insider.

"On top of that, she feels like it's a huge slap in the face that Ryan would remarry this fast. Scarlett is happy and dating, but she assumed he would wait a few years before he tied the knot again," the insider added.
