I wish we had some information on Bellamy's age. He doesn't look all that much younger than Doflamingo. But Doffy is supposed to be 41! - which is somewhat hard to believe judged by his looks. (Heck, he's older than Brook when he died!)

Anyway, if Bellamy is, say, 23 (I'll just assume that he's a bit older than Zoro at most) then this is entirely possible - given that Corazon is only younger than Doflamingo by 1 or 2 years. There is a certain resemblance I guess. But if it's true, Bellamy doesn't know. Otherwise they would have argued with each other differently.
