The 40-year-old pop star said Ethan can swing a club with aplomb and impresses everyone with his sporting skills, reported Contactmusic.
"I don't know who Ethan's going to follow but he loves anything to do with sport. He's got a golf swing on him that Kris has taught him that people cannot believe. He's been doing it for eight months now," she said.
Minogue, who split from Kris in April, said she is not sad about her life because her son and family make her so happy.
"I'm not a misery. Things are great and other people have much harder stuff to deal with than what I'm going through. It's easier when you have an amazing family like I have. My parents are very wise and very calm and always there to guide me."
