Jay Z Is Gonna Be PIZZED . . . After Giving Rihanna That PORSCHE For Breaking Up With CHRIS . . . She's Back With Dude . . . And They're In LO-O-O-O-O-OVE!!!

Yesterday Chris Brown showed the WORLD that he's still f*cking Rihanna . . . by bringing her to the Lakers game on national TV.
Unfortunately for his "GF" Kae . . . she doesn't get the picture. You see on Christmas morning she tweeted out a pic of her in CHRIS' HOUSE . . . wearing his t-shirt and pannies. Just a few hours later . . he was on TV with Rihanna.
