Lindsay Lohan reportedly had a “hissy fit” at the Scandinavian Style Mansion in Beverly Hills on Friday night, claims one magazine.

Page Six spoke with the “peeved” venue owner Claus Hjelmbak. And he is NOT happy with LiLo.

“I’m grossly disappointed in Lindsay for not fulfilling her contractual duties,” Claus tells PageSix.

Oh, and if that’s not enough, he praised Paris Hilton for “taking up Linsday’s slack and stepping up as a last-minute host. “Paris truly saved the night,” he says. “She was very gracious to everyone — and was the life of the party!” “

Why did LiLo reportedly go HeaveHo?

Page Six claims “On Friday night, Lindsay, 21, arrived at the mansion for a fashion event she’d been paid to host, at which 13 posh designers were offering swag to a slew of A-listers.

“But when she spied the words “Paris Hilton Handbags” plastered on the red-carpet event’s sponsor board, she reportedly pitched a fit — and fled the gala less than an hour later.

“Soon after that, 27-year-old Paris herself showed up (with new beau Benji Madden) and stepped into the hosting role. Further irking event participants? Sources tell us Lindsay took some “very expensive gifts” with her before storming out.”

Ahh, no luv for the LiLo.
