The "Love & Hip-Hop: Hollywood" star is calling BS on Ray J's claim that HE bought the whip for her last year. Princess was in Bev Hills -- walking, mind you -- when she claimed SHE paid for it, but Ray J jacked it back.
Princess accepts some of the blame though since she's the "dumb ass" who put the car in Ray J's company's name. But she IS pissed about what he did with it after they split.
Don't cry for her too much -- Princess is strolling into Cartier in this clip.
