Joe Budden's Girlfriend Says He Beat Her Like Rihanna

Rapper Joe Budden allegedly brutally beat his girlfriend the way Chris Brown brutalized Rihanna ... by slamming her head into the dashboard of a car.

TMZ was told Budden saw pics of his GF with some men and flipped out. Sources connected with the woman tell TMZ ... Budden found her at an NYC restaurant, dragged her out to his car and then allegedly choked her and slammed her head into the dash.

The sources say he then drove them to his New Jersey home where cops say the beating continued.

TMZ obtained photos of the GF's injuries ... they're pretty graphic.

Cops are currently investigating.
