Dan Osborne admitted he has done "things I shouldn't have done" as he reflected over the past 10 years.
The reality TV star has been plagued by allegations that he had been unfaithful to his wife Jacqueline Jossa and recently he publicly apologised to the former EastEnders star, saying he has "made some mistakes".
Osborne has now taken to Instagram to look back on the past decade of his life.
He wrote: "How things can change in a decade, I was 18/19 in the first picture, now 28 and a lot has changed, I've turned into 4!
"Haha.. lots of ups and downs in the past 10 years.. been through some tough times but also had some amazing times! Done amazing things that I never thought I would do, also done things that I shouldn't have done, but I'm living and I'm growing as a person and ending this decade with a beautiful wife and 3 incredible children!
"Feeling very lucky! Looking forward to what the new year has to bring and wish you all the very best for 2020 & the future."

Osborne previously admitted that his behaviour had almost cost him his family.
He wrote in a post on social media: "So after weeks, months, years of constant articles and rumours, some true, some very untrue.
"I want to publicly say, I know I have made some mistakes, we all do as humans, but I've made some that have almost cost me my family.
"I have seriously learnt from these massively, so I want to publicly apologise to my beautiful wife and my family for the mistakes I've made.
"I am the luckiest man in the world to have what I have with Jacqueline and my three incredible children and I will spend the rest of my life being the best husband and dad that I can be."
Jossa, who was crowned the winner of I'm A Celebrity... Get Me Out of Here! in December, has also addressed her husband's behaviour, saying he had "done wrong" but that she wanted to "restart their relationship".
