Danny, who is famed for his role as Buster Brady on Mrs Brown's Boys, took to Instagram to pose with his eldest son Jamie who plays for Ulster Rugby's youth side
Most recently Danny's sons, who are grandsons of show creator Brendan O'Carroll, appeared in the live Halloween special which marked Mrs Brown's Boys tenth anniversary.
Although he has given his sons a taste for life as an actor, Danny says there is no pressure for Jamie and Blake 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."
