Andrea Spendolini-Sirieix, the daughter of the First Dates maître d' Fred Siriex, finished seventh in her debut Olympic diving final on Thursday.
The 16-year-old qualified for the finale after making it through Wednesday's qualifying session and finishing eighth in an earlier semi-final which finalised the 12 women who would compete for the medals in the individual 10m platform event.
Andrea, the youngest member of the Team GB diving squad at the delayed Tokyo 2020 Games, scored 305.50 points across her five dives to finish in seventh place.
"I'm so proud I reached the final & I'm happy with my performance," Andrea told the BBC afterwards. "The last 18 months has been a dream. For me, this is the first step and I'm excited for the future."
With foreign spectators banned from attending events in Japan due to Covid-19 protocols, Fred, who shares Andrea and 12-year-old son Lucien with ex-partner Alex Spendolini, cheered on from London.
He tweeted a clip of one of her dives, saying "Well done Andrea" with a duck emoji - a reference to his nickname for the European Championships silver and bronze medallist.
He also added applause to a tweet showing Andrea's placing on the Olympic scoreboard, which saw the Crystal Palace diver place higher than fellow Brit Lois Toulson, who finished ninth.
China's 14-year-old Quan Hongchan won gold in the event with a world record score, beating compatriot Chen Yuxi into silver and Australian Melissa Wu into bronze medal position.
