Frankel's first foal has been born to Group Three-winning mare Chrysanthemum.
The six-year-old daughter of Danehill Dancer gave birth to a bay colt at Coolmore Stud in Ireland on Saturday.
The stud reported that the foal is "a handsome colt with a good head, a white blaze and great presence".
The news has been greeted with great delight at his owner-breeder Khalid Abdullah's Banstead Manor Stud in Newmarket, where Frankel stands.
Juddmonte Farms general manager Philip Mitchell said: "From the reports that I have received, Frankel's first foal is everything we could have hoped for.
"These are very exciting times for everyone who has supported the horse and we much look forward to the rest of his first crop of foals."
Chrysanthemum, who spent her racing days with trainer David Wachman in County Tipperary, was the first mare scanned in foal to Frankel last year, and this is her first foal.
Frankel, trained by the late Henry Cecil, retired from the track in October 2012 after taking his 100% record to 16 with victory in the Qipco Champion Stakes.
Other top mares he has already attracted include Alexander Goldrun, Danedream, Dar Re Mi, Midday, Stacelita and Vodka.
The son of Galileo, now a six-year-old, has an advertised covering fee of £125,000 and mated with 133 mares between February and June in 2013.
Bookmakers have been predictably swift to price up poor-value markets on the fate of Frankel's offspring, with Betfred’s quote of just 40-1 to land the 2000 Guineas at Newmarket in 2017 perhaps the most miserly ‘special’ listed.
