"Real Housewives of New Jersey" star Melissa Gorga is adamant she never, ever STRIPPED during her stint as a bartender at Lookers Gentleman's Club in New Jersey ... and now she's threatening to sue anyone who says otherwise.

Gorga's been hounded by the stripper talk ever since a former Lookers employee began calling BS on Melissa to the media ... insisting she was an exotic dancer at the club.

But Gorga claims she can PROVE she never got naked -- unearthing payroll sheets which list her as a "bar maid" ... and getting a sworn affidavit from longtime club owner Chris Kontos, in which he testifies Melissa "worked solely in the capacity as a bartender."

Gorga has also hired attorney James J. Leonard Jr. -- who tells TMZ, "At this time we are aggressively pursuing the commencement of litigation against any and all individuals, in any jurisdiction, who have or continue to disseminate false statements against Melissa Gorga."

The co-stars are both living the single life now, as Ashton and Demi Moore recently announced their separation following infidelity rumors. Lea also recently split from her boyfriend of a year, Theo Stockman, back in September.

"It was such an honor working with you. I cannot thank you enough," Lea tweeted at Ashton after the premiere.
