According to the certificate, the kid -- born back in January -- officially goes by the name Flynn C.B.C. Bloom ... and those three middle initials are the enigma.
The document lists Orlando's middle name as "J.B.C." -- and we know the "J.B." stands for Jonathan Blanchard. No word on what the "C" stands for ... in Dad's case or baby Flynn's.
Educated guess -- cute?
