Lindsay Lohan won’t be allowed visitors in prison until Saturday

The 'Mean Girls' star – who yesterday (20.07.10) began her 90-day prison sentence for failing to keep up the terms of her probation in a 2007 driving under the influence case – will not be allowed to see any of her loved ones at Lynwood's Century Regional Detention Facility (CRDF) in California until the weekend, and even then at restricted times

Criminal attorney Steve Cron explained: "CRDF has a visiting area where visitors are talking through a glass window through a telephone to inmates.

"It's not intimate or warm and cuddly – but it's easier for the Sheriff's department not to have to put everyone through the same security process."

Visitors are only accepted on Saturday and Sunday from 8.30am to 3.30pm and 5.30pm to 7.30pm.

In addition to no visitors, the 24-year-old star was stopped from taking her favourite novel to jail with her to pass the time.

Lindsay wanted to take in a copy of Ernest Hemingway's 'The Old Man & The Sea', but rules regarding the pertaining of books in prison meant she was not allowed to take it with her.

Meanwhile, Lindsay's father Michael Lohan has revealed the difficulty of seeing his daughter sent to jail.

He said: "It was probably one of the hardest things I've ever gone through in my life. Today is the day that my daughter who I love with all my heart got led out to jail."

Michael – who has also served jail time in the past – also admits Lindsay's younger sister Ali is having a tough time dealing with her being sent to prison but hopes it will deter the 16-year-old aspiring actress from following his elder daughter down the wrong path.

He told RadarOnline.com: "If this doesn't deter Ali from getting into that lifestyle and that limelight, then nothing will.

"It was just as hard seeing Ali and how she reacted to it. She was distraught, she was broken up, she was crying. I think we're all broken up over this."

It is believed Lindsay will only serve 14 days of her 90 day jail sentence due to prison overcrowding.
