Farah's gold medals in the 5,00m and 10,000m in London were arguably two of the greatest moments in an already joy-laden Games for the host nation, and the sight of the athlete embracing his heavily pregnant wife became one of the most memorable images of the 16 days.
The babies - who have yet to be named - were born in London on Friday, and the double Olympic champion was there to witness the happy event.
"My wife gave birth to two little beautiful girls. It is very exciting," he said.
"My wife has been holding on so long and it's great that she held on this long and didn't give birth on the track (at the Olympics)!"
Asked what fatherhood was like compared to winning at the Olympics, the 29-year-old said:
"It's completely different. It's out of your control, it was weird, but as a father I'm very proud. To have three kids in the family is going to be exciting."
Farah is already stepfather to Rihanna, his wife's daughter from a previous relationship, who charmed spectators by celebrating with the runner in the Olympic stadium.
But the athlete will not have long to spend with his new family: the morning after the birth he had to return to Birmingham where he is taking part in a race on Sunday.
