Naya Rivera -- Baby #1 Is a True Outlaw

"Glee" star Naya Rivera and husband Ryan Dorsey might be huge Clint Eastwood fans because their first baby has a definite tie to the ole gunslinger.

Naya and the "Justified" star just had their first kid -- a boy born on September 17 -- and according to the birth certificate ... named him Josey.

Josey Hollis Dorsey ... in full, came into the world at the ever popular celeb birth spot -- Cedars-Sinai Medical Center in L.A.

The name doesn't appear to have any family significance for Ryan or Naya ... so, the most famous male Josey we can think of is ... Clint's character in "The Outlaw Josey Wales."

Congrats.
