Lindsay Lohan embarked on her 30-day jail sentence by turning herself in late Sunday night, and despite promises from the L.A. Sheriff that she would serve time and not be shuffled out due to overcrowding, she served less than five hours. Us Magazine says:

The 25-year-old actress checked into a Los Angeles County jail on at 8:50 p.m. Sunday — and was out by 1:40 a.m. Monday.

Serving a 30-day sentence related to her most recent probation violation, Lohan was behind bars at the County Regional Detention facility for under five hours, thanks to overcrowding.

She will avoid serving an additional 270 days in jail if she performs 12 days of community service at the morgue and attends four psychotherapy sessions before December 14.

But in true Lindsay fashion, before she turned herself in, she came straight from her second Playboy shoot and showed up uninvited to Leonardo DiCaprio’s “J. Edgar” afterparty. The NY Post says:

Lohan insisted she was an invited guest to the party and talked her way past security at the Hollywood Roosevelt Hotel on Thursday night.

A source at the bash told us, “Lindsay was arguing with the security to let her in, dropping every celebrity’s name to get in. She could be heard saying, ‘I have to go and see Leo.’

“Eventually they let her in, but she made everybody uncomfortable. She was aggressive and random, storming around. She tried to get to Leo, but he was surrounded by his security and a posse of his friends.

Lohan’s rep said, “She did not crash, she was invited… she was never asked to leave.”

I once heard a song about this very thing — a stirring ballad about the ails of public rejection and social isolation. It was called “Nobody Likes Me, Everybody Hates Me, I Guess I’ll Go Eat Worms.” I’m pretty sure in Lindsay’s case, “eat worms” is just a nice euphemism for “suck dick.”
