Most likely blown head gasket, is there a mayonaise like deposit underneath the oil filler cap? That would indicate there's water in the engine oil too which just about confirms it. If the head gasket has gone its best to get it fixed quick as you can do more expensive damage as the car will overheat. ..or of course some idiot has put oil in the radiator by mistake in the past.
