Angelina and The Situation were co-hosting an event at Club La Vela in Panama City, Florida -- when patrons began complaining to management about Angelina's behavior.
A rep from the club tells us Angelina was escorted from the property for being "rude to patrons and staff" ... but sources inside the establishment claim the final straw was when the former reality star "drunkenly tried to fight another girl in the V.I.P. area."
Angie left without further incident -- but she isn't permanently banned from the joint ... in fact, she's still scheduled to make a few more appearances in the near future.
UPDATE: Angelina claims she was never in a fight -- but tells us she's pissed at club security for putting her in a headlock when she got involved in a situation involving one of her friends.
Angelina says she's considering taking legal action against the club.
