Djokovic in adorable practice session with son Stefan

Aussie tennis fans will remember Stefan Djokovic from a cute video of him cheering on his dad at the 2015 Australian Open.

Well now he's back!

Ahead of his Round of 16 clash at the Italian Open on Friday, Novak Djokovic hit the practice court, and he brought two-year-old Stefan along for a hit.

The youngster looks to be a long way from emulating his famous father, but he certainly has some skills for a toddler.

Novak was in a much happier mood than he was during his match in which he absolutely unloaded on the chair umpire for a time violation warning.

Stefan has been too young to travel Down Under for the last two Australian Opens, but mother Jelena shared an awesome video of him during Novak's 2015 final against Andy Murray.

The video showed Stefan pointing at the TV screen after seeing his dad, before running away when Murray appeared.

Djokovic isn't the first tennis star to get his kids on the court at a young age.

Could we possibly see Cruz Hewitt and Stefan Djokovic in the 2035 Australian Open?
