Melbourne - Roger Federer had a special guest in his courtside box watching him beat Taylor Fritz - his son Lenny, and he stole the show.
As the Swiss master was doing a courtside interview Lenny was more interested in poking his coach Ivan Ljubicic in the face.
"There he goes. The coach is being very serious, I love that," Federer said.
"I didn't even know he (Lenny) was going to come to the stadium. For me it was a very special match and I'm happy Lenny was there."
Federer has two sets of twins, two boys and two girls, with wife Mirka.
