It seems like the new celebrity trend is making fun of fat people and saying critical things to their faces. Gwyneth Paltrow did it to her “friend” and now this surprisingly explicit Enquirer story claims that Julia Roberts absolutely detests that her half-sister Nancy is overweight. Just to make this clear – I had no problems slamming Gwyneth for her rudeness, because that story came directly from the dude she criticized TO HIS FACE. This Enquirer story might be completely fabricated, but considering the specifics, I’m getting a feeling that some (if not all) of it is true. And if it is true, than Julia truly needs a good, hard slap. I’m not even joking. If she honestly said this this stuff to her sister under these circumstances, Julia is a complete and utter C-U-Next-Tuesday.

Julia Roberts and her half sister Nancy Motes are feuding again – this time over Nancy’s weight! Nancy, 35, has blown up to more than 300 pounds and her movie star sister is “disgusted” by her appearance, say sources.

“Julia’s made no secret of the fact that she’s not happy that Nancy’s gotten heavy,” said a source close to Julia’s husband Danny. “She thinks it’s humiliating for her and the entire family.”

Julia went out of her way to land Nancy a job as a production assistant on Glee, thanks to Julia’s connections with director Ryan Murphy – and Julia believes Nancy’s obesity reflects badly on her, continued the source.

Julia is also concerned that Nancy’s weight will make it difficult for her to continue to care for their 76-year-old mother, Betty, who struggled with her own health issues. While Julia has been paying Betty’s bills, Nancy is her part-time caretaker.

“Julia has asked Nancy point-blank, ‘Who’s going to keep an eye on mom if you get sick?’”

Tensions between Julia and her sister came to a head last month at Betty’s home in Pacific Palisades.

“Julia was rolling her eyes and making cutting comments about Nancy’s weight behind her back – whispering to partygoers, ‘Can you believe how big she’s gotten?’ When Nancy got wind of what Julia was saying, she confronted her, telling her to shut up and leave her alone. Julia shot back, ‘Well, I wouldn’t have to if you had enough self-respect to lose some weight!’ At which point, Nancy told Julia to ‘go f–k herself’ – thus ruining the party.”

The two women have not spoken since, and Nancy was noticeably absent from Julia’s 4-year-old son’s birthday party in June.

So, just to recap, Julia’s sister is the part-time caretaker for their mother, plus she has a full-time job as a production assistant on Glee – which is like a slave position, is very time-intensive, and I doubt Julia really had to pull many strings to get a sister what amounts to an “internship”. And Nancy is struggling with her weight. So instead of lending moral support, or suggesting help in finding a less time-consuming full time job, or suggesting that their mother needs full-time professional help to ease the burden off of Nancy, Julia decides the “solution” is to be a complete and utter bitch DURING A PARTY. And let me tell you something, it was Julia’s d-bag comments that shut the party down. “Well, I wouldn’t have to if you had enough self-respect to lose some weight!” That’s what shut the party down. Not “Go f–k yourself.” Don’t blame the overweight girl for Julia’s ridiculous, THAT’S SO TACKY behavior.

I wouldn’t have even managed to choke out an insult, honestly, if this story is true and I was in Nancy’s position. I would have simply choked the hell out of Julia.
