Lindsay Lohan Spending Thanksgiving With ... Dad?!

Since Lindsay Lohan has been barred from leaving the state of the California during this week's Thanksgiving holiday, she'll be spending it in the Golden State.

With her father Michael!

The troubled star tried to get the permission from officials at the Betty Ford clinic to head back to New York for the holiday, to be with her mother and siblings.

LIKE OLD TIMES: Will Thanksgiving 2010 mark a new, positive chapter in the Lohans' relationships? Or just another bump on an extremely bumpy road to ruin?

Betty Ford wasn't having it though, so she'll have turkey at a home in the Palm Springs where MiLo is staying, close to the rehab center! Miracles can happen!

Michael wants his ex-wife and Lindsay's awful mom, Dina Lohan, and all of their kids to come out and spend the day, but for now, Dina's not interested.

Maybe a Christmas miracle instead?

Could Lindsay Lohan Spend a YEAR in Jail?

Elden Fox has a reputation as a fair justice, but one with the limited or no patience for the defendants if there is any inclination that one has violated his orders.

He's ordered Lindsay Lohan to appear in person at her hearing Friday, even though she's now in rehab and is not planning to dispute her failed drug test(s).

These two facts have Team Lindsay extremely concerned.

Sources say that after all she's pulled, Fox could sentence Lohan to a year behind bars when she appears for her probation violation hearing tomorrow.

Since she was already on probation when she failed the test that have landed her back in the rehab (after a few hours behind bars), he has enough legal leeway.

"Even though Judge Fox has said that any failed drug test would result in an automatic 30 days behind bars, he could go beyond that," a source said.

"Beyond that" could mean flat out terminating her probation.

Lindsay Lohan to Appear in Court, Beg For Mercy

Lindsay Lohan will, at least in the theory, obey the judge's order and appear in the court on Friday morning. But the troubled star's fate there is still TBD.

Sheriff's deputies will be ready to take Lindsay back to jail, if necessary. But things never go as planned with the Lohan, and this case is so weird ... who knows.

In any case, LL will leave Betty Ford Center - where she's been in the treatment since Sept. 27 - to attend her probation violation hearing for a failed drug test.

A source claims Lindsay's legal team won't dispute the violation of the probation (how could they, really) but hope Judge Fox will send Lindsay back to the rehab.

Any interruption, they argue, would disrupt her treatment, as she "has come a long way" at Betty Ford. He could buy that. Or think ... what's the point?

Lindsay is ready and willing to stay in rehab for as long as Judge Fox wishes. If he does send her to the jail, she'll likely get sprung ASAP due to overcrowding.

Once she's locked up, it's largely the call of the corrections office whether she's released early (and she always is). So rehab might be the best alternative.

Michael Lohan Storms the Desert -- Rehab Bound

Michael Lohan has arrived in the Palm Springs ... photographed this morning at a hotel just miles from the Betty Ford clinic where Lindsay Lohan is receiving her treatment ... and has learned he's got a new plan to see his daughter that he intends to execute in just a few hours.

We're told Michael knows it's currently "Family Week" at Betty Ford ... and thinks he should be included in any "family counseling sessions" that go down over the next few days. If Michael isn't allowed inside the clinic, we're told he plans to drop off a letter that he hopes will get to Lindsay.

When called for comment, Michael told us, "If Lindsay's problems stem from me, then I should be involved in the treatment ... right?"

Sources close to the family tell us Dina is currently "on her way" to Palm Springs ... but she'll actually be allowed inside the rehab center.
