Lindsay Lohan in `full denial` over rehab return

Washington: Lindsay Lohan has apparently chosen to ignore her court-ordered 90-day rehab stint by partying in full swing, or, according to one insider, she`s just refusing to believe it is even happening.

The ` Mean Girls` star was recently spotted at a Hollywood hot spot AV Club on Monday night, just mere hours after she was handed the rehab sentence by the court, Fox news reported. A pal of the 26-year-old actress told FOX411`s Pop Tarts column, "Up until last week there was no way she was taking a plea deal, there was no way she was going to go back to rehab, but It`s amazing that she came around." The source added that Lohan is not stupid, it`s just that she is choosing to turn her back to her current situation. ANI
