Bolt, who won eight Olympic gold medals and broke the world record in the 100m, 200m and 4x100m relay, hosted a luxury gender reveal party back in March and later told fans he was set to become a "girl dad".
He has been dating Bennett since 2014 but only went public in 2016, just before he retired from athletics after suffering a hamstring injury at the 2017 world championships.
But there will be no pressure for little Olympia to follow in his footsteps.
"That's going to be hard for my kid. If they want to do it, I'm fine with it," he has said.
"But initially, I'm going to say don't do it, because I know the pressure that will come along with it."
