GREG Inglis has chosen Father’s Day to make a stunning revelation, introducing the world to his secret son.

In the candid post, the 28-year-old Maroons and Rabbitohs star shared how he had fathered Riley in 2009 while he was on a break from now wife Sally Robinson.

Inglis posted an assortment of photos of Riley and told how he had kept him hidden from the public due to the wishes of his son’s mother.

“During a well publicised break in 2009 from my beautiful partner Sally, who is now my lovely wife, I briefly reconnected with my high school sweet heart (sic),” Inglis wrote.

“The result being this awesome and outgoing boy named Riley.

“His mother is a very private person, but now that he has started school, we need Riley to know that I’m proud to call him my son.”

Inglis, who welcomed another son Nate with Sally last year, used the opportunity to call on all fathers to be better at what they do.

“I hope all you dads out there who read this and know they can do better, stand up and be the best father you can be to your child/children.”

The NRL star received an outpouring of support from fans who spoke of their respect for Inglis and wished him a happy Father’s Day.
