Danny O'Carroll and wife Amanda have posed alongside their eldest son Jamie to show their pride in him playing rugby for Ulster.
Mrs Brown's Boys actor Danny shared the picture with Jamie looking so grown up, with fans shocked at how different the teenager looked, reports RSVP Live.
Jamie has starred alongside his mum and dad, who play Betty Brown and Buster Brady on the BBC comedy respectively, since 2012.
Now 15 years old, the Bono Brown actor is growing up fast and Danny and Amanda couldn't be prouder of his sporting achievements.
In a sweet family snap posted on Danny's Twitter account, Jamie could be seen standing tall over his parents as the Dubliner captioned it: "Proud mam and dad. #ulsterrugby."
Mrs Brown's Boys fans loved the picture and flocked to the comments section to send their best wishes to the family.
"Oh wow.. He's grown so much, you must very very proud of him, a lot has happened over the past couple of years, but glad to say that the love of family is still strong.. Good luck to you all," wrote one follower.
"I can’t believe the change in him in so little time, seems like yesterday he was just a little un," a second added.
A third fan wrote: "I’m sure he should be shorter than that and about 10! Lovely photo!"
While a fourth added: "You both look very proud indeed and my word, hasn’t he grown..."
Danny and Amanda are also proud parents to son Blake, 10, who has appeared on Mrs Brown's Boys as well.
Although he has given his sons a taste for life as an actor, Danny says there is no pressure for them to follow in his footsteps.
Revealing that Jamie, who has appeared on the show since he was five years old, almost didn't go through with his role as Bono, he previously told RSVP Magazine: "I remember collecting him from the airport and he said that he didn't want to do it anymore, he was too nervous. I said that it was no problem and he didn't have to do anything.
"I brought him into rehearsals the following day, his grandad had a little chat with him and he agreed to do it.
"From there, he was hooked and everyone wanted him to stay in the cast. He was so good, I don't know where he gets it from [jokes]!"
"As long as they are happy and healthy, I will be happy. Whether they go down the road of acting or not, it doesn't bother me.
"There as one stage where Jamie wanted to be a marine biologist and I was a bit shocked. I don't know where he got that from."
The doting dad went on to say that if his sons decide to go to college, he will support them no matter what.
"Jamie is a very intelligent kid so I hope acting doesn't get in his way if he wants to go to college," he added.
"I will always be there for them no matter what they want to do."
