Jennifer Aniston at loggerheads with Heidi Montag

New York, (ANI): Heidi Montag claims that she wasn't invited to Just Go With It premiere because of Jennifer Aniston.

While A-listers like Aniston, Nicole Kidman and Adam Sandler walked the red carpet at the New York premiere of the movie Tuesday night, Montag was wallowing in her misery. The fame-hungry reality star has a cameo in the new rom-com, but claims that she wasn't allowed to attend the star-studded event.

"I'm so upset. I was so excited! This is the first movie I've ever been in and I can't walk the red carpet because Jennifer Aniston decided I was 'too polarizing,'" the New York Daily News quoted the busty blond, 24, as telling Us Weekly.

"I've been such a huge Jennifer Aniston fan my entire life and it's just really upsetting that she would do this to me," Montag whines. "She should know how hard it is to make a career for yourself and to have someone like Jennifer Aniston go out of her way to make things hard for me is really disheartening."

However, a rep for Aniston, 41, has since shot down Montag's claim, telling Us, "Jennifer has nothing to do with who was or was not invited."
