Una Healy shared some adorable photos as her Tadhg celebrated his fifth birthday.
The singer posted of herself, Tadhg and her daughter Aoife Belle grinning happily at the camera on Instagram.
"Happy 5th Birthday to my darling boy Tadhgy!" she wrote.
Little Tadhg had the time of his life in a Spider-Man costume with a birthday badge and a special Spider-Man cake, RSVP Live reports.
Both youngsters are the image of their mother, and Una's fans couldn't get over the likeness.
"They look just like you, Happy Birthday Tadhg!" wrote one.
"Replicas of you," agreed another.
Meanwhile Una's ex-husband Ben Foden also shared some snaps to mark his son's birthday, writing "Happy 5th birthday to my favourite little man."
Speaking about her children's differing personalities, former Saturdays star Una previously told RSVP Magazine: "Aoife will say that she likes something and she will tell me if she doesn’t like it. I ask her opinion about my outfits sometimes.
"She likes things that are bright and colourful and she always notices if I am not wearing makeup. Tadhg doesn’t say anything."
She added: "Tadhg is a tracksuit man. He is always in a tracksuit and hates wearing jeans. He is huge into Spider-Man at the minute and everything has to have Spider-Man’s face on it."
"Aoife-Belle is still very easy going and she will wear what I choose for her, which is good.
"She is turning seven soon though and that is the time where kids become more individual and decide what they want to wear.
"I tend to keep them quite casual unless there is an occasion."
