UFC stars Conor McGregor & Dee Devlin are over the moon as Conor Jr finishes his first day at school

CONOR MCGREGOR was happy to pick up Conor Jr, his son, from school the first day.

Jr., aged five, attended his first day of school at Dublin School earlier this week after a long family vacation in Spain.

McGregor was proud to share this special moment with his 46 million Instagram followers.

The Notorious shared this picture with Jr. It shows him in his school uniform and Jr holding a well-done certification.

The caption that accompanied it read: "First day at school complete! Proud Dad!

"Good luck to all the children returning to school and their families! It's time to play! Let's go!"

McGregor's fiancée, Dee Devlin, who just got her other half's ink on her, commented with a smiley love heart emoji.

McGregor's follower commented, "Amazing." Good luck Junior, you're gonna smash it."

Another one said, "Conor Jr. enjoys his first school year!"

Another said, "Bravo Conor Jr."

One person commented, "That's amazing!"

McGregor, 33 years old, is currently recuperating from the terrible broken leg he sustained in his UFC 264 Trilogy fight with Dustin Poirier.

A return to the end-of-year was possible, but the Irishman showed that his kicks are still not 100%.

Manager Tim Simspon however, expects him back in the octagon by early next year.

McGregor told MMAJunkie that he was involved in a Road House remake. He said: "A fun little venture, then switching back to climbing on the mountain again."

It fits perfectly. He is still on track to make a huge return next year.

He said, "Acting was not something Conor had in his mind at the very forefront of his mind. Right now, he's still an elite athlete and his focus it to be the best fighters in the world.

"But, as the injury continues healing and he continues to prepare to make a comeback. The timing worked out well.

"It's an amazing opportunity to do a major Hollywood blockbuster in the meantime, and he's going all out to make it a success."
