"It's been a week of educational milestones for my grandchildren. Yesterday, was Philomena's moving up ceremony.

"Thank you to her wonderful teachers, Ms. Vaides (pictured here) and Ms. Leavitt."

He also paid tribute to his old teachers, saying: "I still remember my first grade teacher, Ms. Baird, who helped inspire my love of reading."

The post sparked a huge response from the doctor's fans, including from Philomena's mother, Daphne, who commented with a string of heart emojis.

A fourth fan praised the hard work that teachers do, saying: "Teachers can change a kid's life."

Not only is Dr. Oz a doting father to four children, but he also has four lovely grandchildren, and back in April he shared a rare picture with his son and grandson – and they look so alike!

In the snap, the television doctor sat with son Oliver and grandson Jovan outside a pristine looking house, and the group were all smiles.

Mehmet captioned the post: "Three generations enjoying the sunshine," and his social media followers instantly jumped on to comment.

"Everyone looks alike," wrote one, while a second called them, "triplets" and a third said, "you have STRONG GENES Dr. Oz".

He told that he and his wife Lisa adore having their offspring and their children visit their New Jersey home and admitted: "I like it when the kids run into the house and they can't wait to get in here. It becomes like a beehive."

Before the COVID-19 pandemic struck he told that he considered himself to be a "doting" grandparent and said: "I play with them all the time.

"They want to see me because, when they do see me, they're going to do something fun. I always want to do something active and I want to see how they react if things don't go well."
