Lap Dance Lou has been stripped of his law license.

Former Hot Lap Dance Club boss Louis “Big Daddy Lou” Posner was officially disbarred today for having “knowingly advanced and profited from prostitution” at his infamous – and now shuttered – Midtown jiggle joint.

Posner – who’d managed to wrangle a no-jail deal in his criminal case – contended the loss of his law license was too stiff a penalty, and asked the state Appellate Division for leniency.

In a unanimous decision, a five-judge panel denied the request, saying that since he’d pleaded guilty to a felony – promoting prostitution – the disbarment was automatic.

That leaves Posner without a livelihood.

The portly pimp had at at one point been grossing $22,000 a night with his second job, running his red velvet-swathed W. 38th Street nooky palace. During his guilty plea, Posner admitted he knew some of his lap-dancers were turning tricks in the back rooms of the club, a favorite of lawyers, stockbrokers and wealthy businessmen.

He also admitted “auditioning” new talent, granting himself numerous “comps,” and to personally collecting and pocketing some of his pro’s proceeds.

Posner, who could have faced up to 15 years in prison on the original money laundering charges against him, wound up being sentenced to five years probation and 60 hours of community service – but was barred from ever setting foot in a strip club again.
