No cheers here: The day after Lindsay Lohan taped her pro-sobriety VMA guest spot with Chelsea Handler, the fresh-out-of-rehab star, 24, was back to her old habits, a source tells Us Weekly.

"It's the same old cycle of lying and denials," an insider says of the Machete star, who was spotted at NYC club Boom Boom Room until the wee hours of the night of September 11, just 18 days after she was released from her court-ordered postjail treatment at UCLA's Neurophysciatric hospital.

"She's telling everyone she didn't go out," says the insider. "We're like, 'Lindsay, people saw you there!'"

A witness at the hot spot notes, "It looked like she didn't want to be noticed."

Whether or not the four-time-rehabbed star is truly off the wagon, friends are concerned she's back in the club scene.

"Everything that she went through seems not to have changed her a bit," says the friend. "It's sad."
