Michelle Rodriguez is staying at the fancy schmancy Mayflower Hotel in Coconut Grove (It’s where we had our prom!) and is apparently keeping quite busy during her vacation. Fellow hotel guests were awakened by a loud argument between Michelle and her “roommate:”

“I woke up Sunday morning to the sounds of two women yelling, and one of them was smashing the door knocker very loudly,” one exhausted guest tells us. “I peeked out and saw it was [Rodriguez]. She’s screaming, ‘Open up, let me in, b———!’”

The loud knocking continued for another five minutes, says the source, until the “Girlfight” star hollered, “If you don’t open up, you’re not getting your [pleasure toy] back.” The door creaked open.

The actress did not respond to requests for comment.

Dildo? Vibrator? Anal beads? Battering ram? What’s Miss Michelle into, we wonder. And why is everyone always so eager to immediately link any Hollywood actress with a guy she’s walking across the street from, but with Michelle it’s always “She was eating out her close friend while wearing a snorkel” or “She was giving her roommate a twitty twist while singing ‘Frere Jacques?’”

Anyway. More fun facts about Michelle:

Raised a Jehovah’s Witness along with 10 siblings, Rodriguez plays angry well, in such films as “Girlfight” and “Battle in Seattle.” But when her temper erupts in her personal life, the 30-year-old gets in trouble with the law.

She was arrested in 2002 after allegedly assaulting her roommate, who later changed her mind about pressing charges.

Girl goes through roommates quick.
