Ouch! Gwyneth Paltrow Slammed For Being A Hollywood 'Backstabber' — Find Out Horrible Reasons Celebs Avoid Her

It was one thing for Gwyneth Paltrow to be crowned as Hollywood's most hated celebrity, but now the creator of "Goop" is being nailed for also being one mean backstabber!

According to PageSix, Difficult People creator Julie Klausner revealed that Gwyneth is "all kinds of backstabbing." She even went on to say: "She's into [Eastern therapy] cupping now — maybe she's cupping instead of backstabbing."

And it's not just Julie who has bad feelings about her — earlier this year, she and Julia Roberts were raging at each other. Gwyn became furious when her boyfriend, Brad Falchuk, bypassed her and offered Julia a plum story arc on his Fox series Scream Queens. Gwyn, who met Brad when she guest-starred on Glee, "considered this a betrayal, and she's seething mad," an insider told OK! magazine in January.

Jennifer Garner is also one of the latest A-listers to avoid the actress, too — who both have an ex in common, Ben Affleck. "She's actually told people that she's happy to be cordial with Gwyn, but has no real interest in developing a relationship with her any further — and continually turning her down is becoming more difficult!"

Gwyn proved she could play down-and-dirty mean girl with a shocking move on her ex, and Jennifer Lawrence's boyfriend at the time, Chris Martin. "Gwyneth and Chris had a family dinner out with the kids in L.A. — and JLaw was totally okay with that — BUT found out later from a friend that Gwyneth staged a touchy-feely, post-dinner goodbye that was way too intimate," an insider told the National ENQUIRER in 2014.

And that wouldn't have been the first time Chris' ex has tried to get involved with his relationships. A close pal told OK! magazine last year that it wasn't uncommon for her to bombard his new girlfriends with invitations to hang out and get to know each other. She claims just to be looking out for her kids' best interests, but Chris knows her well enough to see through the act.
