Lindsay Lohan — I Will NOT Party in Dubai

Lindsay Lohan will ring in 2012 at a RAGING PARTY in Dubai — so says an overseas party planning company … but TMZ has learned Lohan claims it’s totally full of crap and now she’s threatening legal action.

Sources connected to Lohan tell us … the actress was PISSED when she learned her name is being used to promote a massive NYE bash on the Queen Elizabeth 2 cruise ship in Dubai … because it’s simply not true.

We’re told Lindsay’s legal team is pounding out a cease and desist letter — claiming she’s prepared to sue the pants off the party people if they continue to lie about Lohan’s NYE plans.

Lohan’s rep, Steve Honig, tells TMZ … “Lindsay is not going to Dubai, nor had she ever considered doing so. She will be spending New Year’s Eve in Los Angeles with a few close friends and family.”

We called the party planners for comment — so far, no response.
