EXCLUSIVE

Kyrie Irving is convinced he's gonna be a dad -- and the baby mama is a SMOKIN' HOT former Texas beauty queen ... this according to court docs obtained by TMZ Sports.

The Cleveland Cavaliers star filed court docs in Texas saying he impregnated 2010 Miss Texas United States Andrea Wilson ... and he's asking for a paternity test to make it official.

FYI -- Wilson has been documenting her pregnancy on Instagram ... and it looks like she's due in December.

Sources connected to the two tell us they've been close since 2013 -- but in the court docs, Irving says they are now separated.

As for child support ... Irving says he wants to step up and cover everything the child needs -- including medical care. But there's one catch, he wants Wilson to raise the child in Texas ... where Wilson and her extended family reside.
