Black Caviar has died.
This is so sad as she stole the hearts and imagination of a lot of Australians.
She died the day before her 18th birthday and just after giving birth to a foal.
Black Caviar had 25 starts over a four-year career, winning all 25 races, including 15 at Group 1 level.
She was added to the Australian Racing Hall of Fame after retiring in 2013, amassing nearly $8 million for prizemoney.
