A few months after Megan Fox and her husband, Brian Austin Green, have decided to end their marriage, is the "Transformers" star hooking up with her "New Girl" co-star Jake Johnson?

According to a report, Megan Fox will be a guest star in "New Girl" while Zooey Deschanel is on leave as she is pregnant.

"The 'New Girl' hook-up session was recently filmed with Johnson and Fox for an upcoming episode and the two stars were looking like they really got into it," Celeb Dirty Laundry reported.

"After the scene as Fox walked off set, Jake Johnson was seen with a pouty look on his face. He clearly didn't want Megan to go," the report continued.

Is Megan Fox's husband furious over the alleged hook up?

"We're pretty sure Jake's wife of almost a decade hopes that doesn't happen. Jake Johnson has been married to artist Erin Payne since 2006 so he's officially off the market," the report added.

A few months ago, a source close to Megan Fox's husband claimed that the actress has allegedly had an affair with Shia LaBeouf and that Brian Austin Green was allegedly aware about it.

"Brian has always been wary of what Shia's capable of," the insider previously told Dish Nation. "After he shot his mouth off about his on-set romance with Megan while Brian and her were split, there were significant issues."

According to the source, Megan Fox and Shia LaBeouf has been pretty close again these past few months.

"Megan started speaking to Shia about a year ago when the two of them were going through troubled times. Shia was off the rails, boozing heavily, and leaned on Megan for support," the source added.

"Her movie career was dwindling, and she went to him for advice after a series of film flops, and the two were able to comfort one another."

According to Brian Austin Green's friend, Megan Fox and her husband were also facing other troubles aside from the actress' closeness with Shia LaBeouf. But Megan and Shia's alleged affair was what purportedly drove Brian to end it with his wife.
