Kris Humphries sicked his lawyer on the fancy New York City hotel his ex-girlfriend works at, telling the manager that Myla Sinanaj ran a brothel out of the hotel and had sex with hotel guests … so claims Myla’s lawyer.
Joe Tacopina, who now reps Myla, tells TMZ … Kris and his lawyer have been on a search and destroy mission against his client, trying to hide the fact that they have been in a relationship for 5 months.

Tacopina says Kris’ lawyer called the hotel manager last week and made the claims.  Tacopina believes Kris and his lawyer wanted to get Myla fired, to make a point that she had better shut her mouth about her relationship with Kris … or else.

By the way, sources connected with Kris confirm his lawyer made the call.

We’re told hotel management investigated and quickly determined the allegations were baseless.

Tacopina tells us … a defamation case against Kris now looms large, and he had better apologize quickly for what he says is shameful, vindictive conduct.

But a source connected with Kris tells TMZ, “He will not be apologizing.”
