Jennifer Aniston is pulling out the potty mouth to get tabloid snitches to quit starting pregnancy rumors about her.

“It’s almost going to take away the fun from actually being able to say one day, ‘I’m pregnant!’” the Marley & Me star told Entertainment Weekly in the magazine’s December 12 issue. “Everyone will be like, ‘Yeah, right.’ It’s the boy who cried wolf. Stop stealing my thunder, motherfuckers!”

You kiss John Mayer with that mouth?!
