They stand to win the top prize of $20,000 and a chance to symbolically flag off the race in Singapore.
On the show, the girls will take turns to fly to different F1 races around the world before the competition arrives in town.
Says undergraduate Lim Wei Ling, 22, who will be going to the Hungarian race next month: 'I'm very excited about the trip and I want to meet the drivers.
'I love Formula One and have been a long-time supporter of Jensen Button.'
Another grid girl, flight stewardess Desiree Yong, 24, says: 'Apart from meeting the drivers, it is the overall experience of being part of the F1.
'It is a once-in-a-lifetime experience.'
