RING AROUND THE PINKY
Post Malone is celebrating a new addition to his already impressive jewelry collection -- a blinding 23 carats worth of diamonds, and all that bling is just for the littlest finger of them all.
Guess his hand was feeling a little light, because sources close to Post tell TMZ ... he called up his pals at Angel City Jewelers to hook him up with a new piece for his pinky.
Angel City's owner, Isaac Bokhoor, came through with the goods while PM was making a recent tour stop in Las Vegas .
