Brad Pitt is not cheating on his wife Angelina Jolie, Gossip Cop reported late Monday debunking a report that said the actor was caught kissing his co-star Lizzy Caplan during the shooting of a film in London. Rumors have been doing the rounds for several months about tensions between Jolie and Pitt, with some reports speculating the couple is heading for a divorce.

Radar Online reported that Pitt was spotted passionately kissing Caplan while the two were filming a scene. However, Gossip Cop slammed the report, saying that the photos posted by Radar Online show Pitt kissing his “sister” on the cheek. Gossip Cop also debunked claims that Pitt and Jolie have been “at war over who’s looking after the kids.”

Pitt and Jolie's divorce rumors come amid growing concern over the "Maleficent" actress' health. According to reports, Jolie's weight has come down to 79 pounds. Some speculate that the reason behind Jolie's health crisis is her marriage trouble.

The National Enquirer earlier reported that Pitt was "at the end of his rope" over his wife's reluctance to address her health issue.

"Brad has done everything to get Angie to focus on her health and well-being," a source told National Enquirer. "He's watched in despair as Angie sometimes goes all day without eating a solid meal and watched as well as she's sometimes slept in to the late afternoon because she doesn't have the energy to get out of bed."

Amid rumors about divorce, Star magazine reported that Pitt was getting cozy with his co-star Marion Cotillard. The report also said that Pitt and Cotillard have “affectionate nicknames” for each other and “secret in-jokes that no one else gets.”

Several reports have said that Jolie was paranoid over Pitt's flirting, and this was tearing their marriage apart.

OK! Magazine reported last month that Jolie didn’t want her husband to hang out with Ben Affleck because he is a “bad influence.”

“Brad in particular is excited to have someone to go drinking with, [but] Angie thinks Ben is a terrible influence,” an insider told the magazine. “Angie thinks Ben’s single status spells trouble. She doesn’t want Brad playing wingman, so he’ll be on a very short leash.”
