I'm Throwing A Big Party for My Dog,No Ladies Allowed - Ray J

Ray J is throwing a lavish birthday party for the dog he once shared with Princess Love, but he's laying down the law ... she's not gonna screw this pooch.

First the party ... Boogotti the Maltese will be the birthday boy at a $30k blowout at Petrock Hotel and Spa in Encino, CA. He's pulling out all the stops -- a red carpet, a dog treat station and a special cake for pooches. There will also be plenty of human food.

But Princess Love won't be seeing Boo all gussied up in his tux, because she's not invited. The 'Love and Hip Hop' stars had a bitter break up after she bolted with Boo's 3 Maltese mates. They tried working things out but they're on the outs again.
