Shaunie O'Neal is giving her ex-husband, Shaq, a little automotive advice ... pump your brakes, big fella ... saying guaranteeing both their kids make the NBA is too much pressure to put on the boys.
The Diesel made the big boast to us last week ... saying 16-year-old HS hoops superstar Shareef O'Neal AND his little brother 13-year-old Shaqir were LOCKS to hoop in the NBA one day.
We got Shaunie O'Neal out at LAX recently and asked her thoughts on The Diesel's big prediction ... and she sung a little different tune than Shaq did.
Check out Shaunie go all mama on our camera guy ... saying both kids know their dad is a big talker, and Shaqir is thinking about a much more important thing than b-ball right now ... girls.
Still though, we gotta say ... we like the boys' chances ... if they're into the whole millionaire thing, that is.
