The Hell's Kitchen and MasterChef judge's wife, Tana Ramsay, gave birth to a son on Thursday.
"After 3 baftas and one Emmy... finally we have won an Oscar, please welcome Oscar James Ramsay, who touched down at 12:58 today for some lunch ! Xxx," Gordon, 52, captioned a series of photos of the couple and their new baby in the hospital.
The celebrity chef shared four new photos of the newborn, including two of his beautiful 44-year-old wife smiling at little Oscar.
Oscar joins Gordon and Tana's other children -- Megan, 21, twins Holly and Jack, 19, and Matilda, 17.
The couple announced in January 2019 that they were expecting again less than two years after Tana suffered a miscarriage.
"Exciting news ! Happy new year from all the Ramsay's," Gordon captioned a video of his children panning down to Tana's baby bump.
"And guess what, happy new year because we've got another one coming. Oh, my lord!"
Gordon and Tana were able to conceive less than two years after a devastating miscarriage.
They sadly disclosed in June 2016 they had lost a baby five months into her fifth pregnancy.
Gordon, who also serves as a judge on MasterChef Junior and stars on 24 Hours to Hell and Back, shared on Facebook at the time, "Hi guys, Tana and I want to thank you so much for your support over the past couple of weeks."
"We had a devastating weekend as Tana has sadly miscarried our son at five months," he continued.
