Robbie Williams was once known as the bad boy of British pop.
But now he's living the dad life and his three children are at the centre of his world.
So much so, the former Take That star, 45, posted an emotional tribute to his kids on Father's Day.
In the post, Robbie shared a pic of him and two of his three children - Teddy and Charlie - as they played with a dolls house.
He accompanied the image with this heartfelt tribute.
My children have turned my world upside down.
"My children have turned my world upside down," he said.
"For my family I want to be the best version of myself."
Referencing Weight Watchers, who he's an ambassador for, he also said: "I have changed so much since the beginning of the year - quit smoking, learned new healthy habits that I hope I can pass these on to my family. Thanks @ww.uk."
Many of his 1.9million followers took to the social media site to express their delight.
"Give yourself a big pat on the back, it’s never easy giving up our vices but you have done good for the future of your family, keep up the good work RW, enjoy family time," one said.
Another commented: "You are doing amazing. Great wife and gorgeous kids, what more could you ask for."
Finally, another follower said: "You've found your place in life. So happy for you, lovely family."
At the weekend, Robbie showed off his toned body in a poolside snap, complete with budgie smugglers.
Meanwhile, speaking to the Daily Star newspaper, he said of his new healthy lifestyle: "Back in the '90s, it used to be strippers and cocaine and now it's hummus and celery and my life is much better for that.
"I used to live on rock star hours, which was go to bed at three or four o'clock in the morning, and wake up in the afternoon.
"You quickly realise when you have a child you are not an insomniac but a bit lazy and prone to exaggeration."
