According to TMZ, the possibility of an arrest warrant is very real for Lindsay Lohan if she doesn't report to her rehab facility by tomorrow morning.

It was reported earlier today that the much maligned actress arrived at Morningside Treatment Center in Newport, Calif. today but never got out of her SUV.

If Lohan isn't present at the facility by 6am, prosecutors will head straight to court first thing tomorrow to seek a warrant for her arrest.

Let's hope she gets her act together and quick!
