Michelle Rodriguez in Hotel Room Fight with Female "Friend"

Michelle Rodriguez may not think it's anyone's business who she sleeps with (regardless of if it's "a girl, a boy, [or] a dog"), but apparently it's everyone's business who she fights with—whether they like it or not.

The bad-girl actress got into a shouting match with another woman at the Mayfair Hotel in Coconut Grove, Florida early in the morning on Sunday, awaking fellow guests when she was apparently locked out of her room by banging loudly on the door and screaming.

"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 Rush & Molloy. "I peeked out and saw it was [Michelle]. 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." That seemed to do the trick, as the door opened and the shouting stopped.

Pretty classy, Michelle. Here's a hint: if you don't want people gossiping about you, maybe try keeping your personal life behind closed doors, huh?
