Ray J -- I Got A New Baby Too ... Furry Edition

Ray J and Princess Love welcomed a new baby boy of their own to the family this weekend ... and he's got four legs.

Sources at the Chelsea Kennel Club in NY tell TMZ the two came in with some friends Friday looking for another maltese. However, PL locked eyes with a chihuahua one of the shop's employees was holding and fell in love.

We're told the dog weighs less than two pounds and cost right around $2,000.
