Venus and Serena are the current Olympic champions in doubles
Venus and Serena Williams won their eighth doubles Grand Slam title with victory at the Australian Open.
The sisters brushed aside Daniela Hantuchova of Slovakia and Japan's Ai Sugiyama 6-3 6-3 to claim the trophy for the third time in Melbourne.
"I'd like to thank Serena for being the best partner," said 28-year-old Venus. "I wouldn't want to play with anyone else. She's amazing."
The Williams sisters also won the Olympic doubles titles in August.
On another roasting day in Melbourne, the Rod Laver Arena roof was closed for Friday's doubles final.
The Williams sisters, seeded 10th, breezed through the first set in 38 minutes.
The second set was more hard-fought as the pairs exchanged breaks six times in nine games before the Williams came through.
