The restaurant heir, Harry Morton has reportedly split up with high-profile actress Lindsay Lohan at the Chateau Marmont after dinner yesterday, according to sources.

A source told people that the break-up was due to: "She was too much drama. Lindsay did cut down on the partying, but with her it's all relative. Harry is sober. It wasn't the partying that broke them up. She's young and a little bit immature. Harry's more low-key and not into the same stuff she's into."

Multiple sources add that Lohan, 20, was seen running onto the patio at Hollywood's Chateau Marmont to her friends and weeping with a tissues and a cell phone on hand.

"She ran in, sat with her group, put down her cell phone and cried to her pals," an observer told People, "The group looked very concerned and listened intently to what she was saying."

Lohan's representative told People that, "The story is untrue."

On the other hand, Morton's representative said, "I do not comment on his personal life."

Actress and pop singer Lohan and Morton started dating on July 2. Morton, 25, is the owner of the restaurant chain Pink Taco. He is the son of former Hard Rock Cafe chain owner Peter Morton.
