Gordon Ramsay’s son is celebrating a special day!

On Thursday, the celebrity chef, 57, shared a photo on Instagram as his son Oscar celebrated his fifth birthday. Carrying Oscar on his shoulders, Ramsay smiles for the camera and holds his son’s stuffed animal.

Oscar grins on his dad’s shoulders, bearing a striking resemblance to the TV personality. “Happy 5th Birthday to this little man @oscarjramsay love you so much OJR Dad ❤️❤️❤️,” Ramsay wrote in his caption.

Alongside son Oscar, Ramsay is dad to daughter Megan, 25, twins Jack and Holly, 24, daughter Matilda “Tilly,” 22, and son Jesse, 5 months, whom he shares with wife Tana.

Last month, the proud dad shared an adorable photo of his son Oscar as he dressed up as Paddington Bear to celebrate World Book Day.

Wearing the fictional bear’s iconic blue jacket, red boots and matching red hat, Oscar completed the costume with Paddington’s suitcase and a little tag that read, “Please look after this Bear. Thank you.”

“Happy world book day @oscarjramsay ❤️,” Ramsay wrote in his caption.

Back in January, the celebrity chef spoke with PEOPLE and shared whether he’d be open to welcoming a seventh child into the mix.

Telling a funny anecdote about son Oscar, the dad of six revealed, “This morning, Oscar said, ‘Wouldn’t it be nice if Jesse and I had a little sister?’ And I spat my Cheerios out. So yeah, I had to get up from the table and walk away.”

“I didn’t wait to see Tana’s reaction. I literally coughed my Cheerios out all over the table,” he added, before teasing, “So yeah, listen, who knows, right?”
