Mozambique's Maria Mutola became the first athlete to win the $1m Golden League jackpot by winning the 800m in Brussels on Friday.
The 30-year-old won in a time of one minute 57.78 seconds to claim her sixth consecutive League victory of the season.
Natalya Khrushelyova, bronze medallist at the World Championships, was second in a time of 1:58.53, with Morocco's Amina Ait Hammou third in 1:58.66.
Despite running 1:58.69 - her fastest time of the year - Kelly Holmes, the silver-medallist in Paris, finished fourth.
Mutola was fifth at the bell, but she moved into second place along the back straight before producing a magnificent finale.
Entering the final 100m with a metre advantage, the world and Olympic champion streaked down the
home straight to claim a historic victory.
To collect her winnings, Mutola must compete in the World
Athletics Final in Monaco from 13 to 14 September.
Double world sprint champion Kelli White put aside the problems surrounding her positive drugs test to win the 100m in Brussels.
White got the better of her rivals in Brussels
The American tested positive for a stimulant after her victory on 24 August and could still be stripped of the gold medals she won in the 100m and 200m in Paris.
But she was given the green light to compete in Belgium by the International Association of Athletics Federations and, cheered on by a supportive Belgian crowd, she triumphed in a time of 10.87 seconds.
Fellow American Chryste Gaines was second with Torri Edwards, who would be named world champion if White is stripped of her
medals, in third.
British number one Joice Maduaka - a late entrant for the race - was ninth and last in 11.48.
Newly crowned world 3000m steeplechase champion Saif Saeed Shaheen was again in brilliant form.
Shaheen, who caused a stir when taking up Qatar nationality after being guaranteed a pension of $1,000 for the rest of his life, ran the fastest time in the world this year of eight minutes 0.06secs.
Hayley Tullett, who was a surprise bronze medallist in Paris, finished second last in a 1500m race won by Turkey's Sureyya Ayhan in 3:55.33 - the best time in the world this year.
Mark Lewis-Francis and Dwain Chambers were sixth and seventh in a men's 100m won by Jamaica's Asafa Powell.
