Life & Style claims that Heidi Montag wants to sue the creator of The Hills for sexual harassment stemming from a late March incident on the set of The Hills in which she claims he groped her. On the day in question, Heidi was called out by US Weekly for bringing six bodyguards with her on set and refusing to pose with her costars for a group photo. Heidi’s husband Spencer explained the incident by claiming that Heidi was sick and that she “always travels with a security team.” Now Life & Style claims that Heidi thinks she was continually sexually harassed by her boss and that’s why she brought so many guys with her to work. A “source” is telling Life & Style that Heidi plans to sue, but it doesn’t sound like she’s actually done so yet.

Life & Style can exclusively reveal that an incident at last month’s photo shoot for The Hills sparked Heidi Montag’s plan to sue show creator Adam DiVello for alleged sexual harassment.

It happened the last weekend of March, during a cast photo shoot to promote the sixth and final season of The Hills, an insider close to Heidi tells Life & Style. “Adam came up to her from behind and grabbed her with one hand on her stomach and one hand directly on her butt cheek,” the insider claims. “Heidi had six bodyguards with her. They took his hand off her and moved him away from the situation.”

Heidi refused to go ahead with the photo shoot, a move that got her labeled a diva in online reports. Heidi’s husband, Spencer Pratt, issued a statement on March 29, saying Heidi “was sick and she didn’t even want to go to that photo shoot.”

The insider tells Life & Style that Heidi claims she’d been annoyed with DiVello for a while. “Heidi started bringing security to the set because she felt Adam was getting a little creepy. He was very touchy-feely and she insisted he wouldn’t stop asking her to strip down to a bikini for scenes. Adam wasn’t on set much for six seasons until Heidi got her new boobs. And now he shows up everywhere.”

After the incident, the insider claims, “Heidi and Spencer e-mailed the production team and asked to talk about what happened. But after three weeks they’d gotten no response other than to say Heidi was allowed to bring only one bodyguard on set.

“Heidi’s been in tears about it and really upset because she says she doesn’t feel safe,” the insider continues. “Heidi says she wanted to solve the issue behind closed doors but The Hills just wouldn’t talk about it.”

Another insider says it’s been discussed on set that DiVello may use his position with the show to get close to young women, claiming, “You have to stroke his ego to get a big role on his shows.”

Meanwhile, co-star Lo Bosworth tweeted her take on the matter: “I’ll repeat it: no one is/has ever been assaulted during filming of our show. hey spiedi, do you know the definition of slander? NOT OKAY.”

I wouldn’t put it past Heidi to make something like this up. Or at least Spencer might make it up and ask Heidi to go along with it. However, all we have for now is hearsay in Life & Style. Heidi and Spencer haven’t said anything about this, although of course I suspect them of going to Life & Style with this story. As much as it pained me, I went to Heidi and Spencer’s respective Twitter accounts and they haven’t said anything about this yet. They’re sure to chime in once they wake up this morning. It’s suspicious, though, that Spencer was barred from the set for six weeks for screaming at a female producer and now we’re hearing these sexual harassment claims.

Oh, and sexual harassment is wrong and we should take these allegations seriously despite who they’re coming from etc., but I have to say something snarky about how Heidi probably couldn’t have even felt it if someone groped her on the boobs or stomach. That sh*t is pure plastic.
