Controversial tennis star Nick Kyrgios has apologised after making on-court remarks about his opponent's girlfriend.
He has been fined by governing body, the ATP, after aiming comments towards Stan Wawrinka during a match at the Montreal Masters.

Microphones picked up Kygrios, who courted controversy at Wimbledon, telling two-time Grand Slam champion Wawrinka: "Kokkinakis banged your girlfriend, sorry to tell you that mate".
Thanasi Kokkinakis (19) is a fellow Australian tennis player, while Wawrinka's girlfriend is Croatian player Donna Vekic.
