Heidi Montag was a major diva at a weekend Hills photo shoot, Spencer Pratt confirms to UsMagazine.com.
PerezHilton.com reported earlier Monday that Montag, 23, showed up with four bodyguards and "Audrina [Patridge], Kristin [Cavallari], Stephanie [Pratt] and Lo [Bosworth] were all shocked." She then "refused to take part in a group shot, even though she had agreed to it beforehand." (MTV will Photoshop her in later, it was reported.)

Pratt, 26, tells Us, "It's all true. She was sick and she didn't even want to go to that photo shoot!"
Montag posted a photo of her posing with six bodyguards on Facebook. Pratt says her entourage is nothing new.
"She always travels with a security team," he explains.
When asked about her behavior, a source tells Us she replied, "I'm a movie star now!" (She just finished filming her cameo on Just Go With It, which stars Jennifer Aniston.)

Another source close to the reality couple tells Us, "Spencer's been banned from the set... so Heidi feels safer with her security team around."
Pratt was forced to take a six-week leave after "flipping out" on a female producer after she made a request he objected to, an insider told Us last week. "He got so crazy that he screamed at [her], 'I should kill you for even asking me to do that!'"
