Michelle Rodriguez's momma must not have taught her manners!!!

The drunk-driving actress was a guest at the Mayfair Hotel and Spa in Coconut Grove, FL, this past weekend. Sources say she was spotted hanging out at the hotel pool and a Friday-night party with a "very pretty" Latina.

She's a lesbian? Shock!

ANYWAY, on to the real juice! Michelle was reportedly quite rude this past Sunday morning.

Fellow guests say they were awakened at 9 a.m. Sunday to loud banging and Rodriguez screaming at the top of her lungs to her, uhmm, roommate.

One of the guests reports: "I woke up Sunday morning to the sounds of two women yelling, and one of them was smashing the door knocker very loudly. I peeked out and saw it was [Rodriguez]. She's screaming, "Open up, let me in, bitch!"

The snitch said the loud knocking continued for another five minutes until the former Lost star threatened, "If you don't open up, you're not getting your [pleasure toy] back."

No joke, that's when peace descended and Michelle's 'roommate' opened the door.

Hope they learned to share and had lots of fun with the toy!
