EXCLUSIVE

On Sunday night, Jason Preston shocked the Hot Messes at his weekly Sunday night party at Porky's by showing up with Erik Rhodes on his arm.

Yes, Rhodes is the porn star that Page Six revealed was sleeping with Preston's boyfriend, designer Marc Jacobs.

A source very close to Jason and Marc tells us that Page Six got the story all wrong. Evidently both Preston and Jacobs were screwing Rhodes.

"Jason and Marc have both bragged about hooking up with Erik at the same time," our source revealed.

Sounds like a very interesting love triangle to me! It is amazing what money can buy these days.

I ain't sayin' they're gold diggers... I'm just saying.

UPDATE: Is it finally over for Marc Jacobs and Jason Preston?
