If it looks like a duck, and quacks like a duck ... it's cutie Gannon McKee!
Teen Mom 3's rumored new cast member, Mackenzie Douthit posted this pic of her baby boy sporting an adorable duck costume.
"Don't ask... I have a crazy aunt who buys him funny stuff #quack," she wrote in the caption.
Well, if Gannon's gonna look this darn precious, we think the crazy aunt should buy him even more funny outfits!
