Lindsay Lohan Prepares To Leave Rehab, Tweets Message Of Hope

We can hardly believe it: Lindsay Lohan is just a day away from freedom! She's been undergoing rehab treatment at the Betty Ford Center since October, and will be able to leave the facility (hopefully for good) tomorrow.

It looks like the troubled starlet is already getting back into the swing of things, and even resurfaced on Twitter yesterday to write a motivational blurb about the future -- with a little help from Ghandi. She wrote: " "Today is the first day of the rest of my life. 'The future depends on what we do in the present.' Lindsay+Lohan in Lindsay Lohan Shops in Palm Springs-Mahatma Gandhi… One step at a time…"

Word has it LiLo will go into hiding once she's free from rehab, then will resurface in public when the time is right. Best of luck, Lindsay!

Kate Winslet Has a New Man

Kate Winslet is apparently dating someone new! She and Burberry model Louis Dowler called it quits a few months ago, and sources say the actress and a mystery man enjoyed a 3-hour lunch in London recently.

An onlooker told The Mail on Sunday newspaper: "Kate enjoyed oysters and a chocolate fondant dessert - she was eating the food of love. She looked very content. They were chatting for hours. She was in fits of giggles at one stage and then later they looked very serious together. It seemed they were having an in-depth discussion and she clasped his hands over the table. When Kate finally paid the bill, it was getting dark."

When the pair - who have known each other for years - finally left, they asked waiters to arrange for them to leave separately as they didn't want anyone to see them together.

The 'Titanic' star split from Louis in November saying she wanted some time alone following the breakdown of her marriage to director Sam Mendes in March.

A source close to Kate - who has a seven-year-old son, Joe, with Sam, as well as a 10-year-old daughter, Mia, from her first marriage to Jim Threapleton - said of the split: "Louis was just the tonic Kate needed after her painful split from Sam and they had a wonderful time. However, the relationship isn't working and Kate needs space to be on her own. She is very grateful to Louis for helping her pick her life back up after her marriage ended and they had a lot of fun together, but she felt it had come to an end and wants to concentrate on her career and children."

Michael Lohan Worried Lindsay Will Relapse If He And Her Mom Don't Start Getting Along

Michael Lohan is keen for his troubled daughter to stay sober when she leaves her court-ordered stint at the Betty Ford Clinic next week. He's spoken with Lindsay's advisors to help persuade his ex-wife Dina to agree to meet with him so they can put their problems behind them.

He said: "I am getting in touch with Lindsay's team, including Tom Hansen, Blair Berk, Lou Taylor and Shawn Chapman Holley, in the hope of trying, again, to have them persuade Dina to sit down so we both can iron out our differences.

"Quite frankly, everyone knows this, including all the counselors and therapists. Dina and I need to get along and put our differences aside if Lindsay is going to have any chance at a full recovery without relapse."

Michael has urged Dina -- who has repeatedly accused him of failing to pay child support for their youngest kids, Ali, 17, and 14-year-old Cody -- to forget about their previous problems and put their family first by staying civil to one another.

He added to RadarOnline.com: "Everyone has been asking Dina to sort out her issues with me, but the general consensus is that she simply can't admit or take responsibility and she is afraid to do so.

"But that isn't even part of it, she doesn't have to admit anything. All she has to do is keep Lindsay and the kids out of our differences and try to get along for their sake.

"She can make all the claims she likes about child support -- the truth of which is that every cent owed has been paid and even more -- but there is a much deeper and important issue here: Lindsay's health is first and foremost. Our kids are first and we should be second."

Witherspoon has been the subject of plenty of wedding rumors recently.

She joked about engagement chatter to Entertainment Weekly, saying "My mom always texts me, like, 'Are you getting married?'" Witherspoon said. "I'm like, 'Mom, come on! You would know if I was getting married,'" she said.
