Gordon Ramsay has become a father for the sixth time at the age of 57, welcoming a 7lb 10oz "whopper" of a son to the family.
The TV chef and his 49-year-old cookery book author wife Tana announced the birth of Jesse James Ramsay on Instagram on Saturday.
Ramsay, who celebrated his birthday on Wednesday, called the newborn's arrival "an amazing birthday present" - although it is unclear when exactly Jesse was born.
He and Tana, who have been married for almost 30 years, are also parents to Megan, Matilda, twins Jack and Holly, and Oscar.
The chef strongly hinted this would be his last child, writing on Instagram: "One more bundle of love to the Ramsay brigade!! 3 boys, 3 girls.... Done."
In a separate post to her 295,00 followers, Tana revealed the pregnancy had been "a nerve-wracking nine months", adding: "but we've made it and we have been blessed with this little bundle."
She also appeared to confirm it would be their final child, adding: "Ramsay family definitely complete.
"Jesse James Ramsay we love you so much."
The couple were quickly congratulated by fellow celebrity friends and fans alike.
Fellow chef Jamie Oliver wrote: "Wow super mum congratulations!" along with clapping hands emojis.
TV chef Gino D'Acampo wrote: "FANTASTICO, still plenty of lead in that pencil!"
Victoria Beckham wrote under Tana's post: "Congratulations xxx we love you all xx"
In 2016, Ramsay and Tana experienced a pregnancy loss at 20 weeks.
"Born with a strong heartbeat but too little to survive," Tana said of their son, who they named Rocky.
