LIFE STYLE EXTRA (UK) - Lindsay Lohan has split - and got back together - with Harry Morton.

The break-up, which lasted less than 24 hours, happened when he reportedly dumped the 'Mean Girls' actress after dinner at the lavish Chateau Marmont in Hollywood on Thursday night (21.09.06).

A source told People magazine: "She ran in, sat with her group, put down her cell phone and cried to her pals.

"The group looked very concerned and listened intently to what she was saying."

A friend of Harry's revealed: "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.

"Harry's more low-key and not into the same stuff she's into."

However, a source close to Lindsay has denied the pair split at all.

The source insisted: "No one 'dumped' anyone. You don't dump people when you're 20 and 25. You have a mature relationship, and you take a break and you see what happens."

Meanwhile, Lindsay upset Harry earlier this month by flirting all evening with the DJ at the party at the swanky English manor Cliveden House.

Lindsay left Hard Rock heir Harry fuming after spending the entire night glued to Sam Young.

One guest said: "She was all over him like a rash."
