Did the "Fifty Shades Darker" star Dakota Johnson hooked up with Heidi Klum's boyfriend?

After the success of E.L. James movie adaptation of "Fifty Shades of Grey," one of the most sought-after star is Dakota Johnson who portrayed the role of Anastasia Steele in the controversial movie and part of the fame that her character induced is the tabloid's speculation on her lovelife.

According to Enstars, Johnson was recently linked with Heidi Klum's boyfriend Vito Schnabel. The scoop says that Schnabel was seen being "close" and cozy with the 26-year-old "Fifty Shades of Grey" star in a Manhattan writer's hangout. This rumor apparently was backed up by onlookers and Schnabel's girlfriend model Heidi Klum is furious with the news when it reached her.

"Heidi is furious over claims that Vito and Dakota have been hooking up together behind her back. Eyewitnesses apparently spotted the two packing on some serious PDA at Manhattan's White Horse Tavern this past week," according to the outlet based on Star Magazine.

The sources dished, Johnson and Schnabel were seen "holding hands" on and off.

"They even held hands on and off," said the sources of the magazine. "She couldn't contain her affection for him. At one point, she hooked her thumb onto his pocket and put her head on his shoulder."

Insiders even added the tension over the event when they said that Schnabel didn't brush off the sweet gesture of Johnson and even "held" the "Fifty Shades of Grey's" actress' hand.

"He didn't reciprocate the touching as much as she seemed to want, but he held her hand and at one point pushed her hair behind her ear," the sources of the outlet added.

Last Sept., Johnson confirmed in "Ellen's" show that she was currently "single" and that she finds it hard to find her luck in the dating scene. One of the reasons that Johnson stressed was due to her racy role as Anastasia Steele in "Fifty Shades of Grey."

But are the sources true that Johnson is now into Klum's boyfriend Vito Schnabel?
