Made In Chelsea's Spencer Matthews thinks it's time he "grew up".
The 26-year-old star - who has earned a reputation as a "lothario" on the show - thinks he's reached an age where he needs to be more serious.
Speaking on ITV show 'This Morning', he said: "I can't make any promises, but I'm trying to be a nicer person.
"I just think it's time to grow up - I'm 26 years old now - so for me gallivanting around being a 'lothario' as it's being referred to, is just a bit ... I'm trying to be a bit more serious."
The reality television star - whose family owns the exclusive Eden Rock Hotel in St Barths - admitted he fell for the same girl as his co-star Stevie Johnson when they were filming for the show in New York last month.
He confessed: "Yes, we both took a liking to her ... but we managed not to fall out."
Spencer first got his nickname as a "love rat" when it was revealed that he had cheated on two of his ex-girlfriends, Lucy Watson and Louise Thompson, within a few months of each other.
He made the admission about Lucy during the filming for the 'Made in Chelsea End of Season Party' last year.
At the time, he said: "I've slipped up. I've cheated on her ... I think I'm just young and living some form of dream but unfortunately hurting people in the process."
He continued: "If anyone could have changed me, I still think it could have been her - could still be her.
"It's a horrible thing to do to someone who deserves it as little as Lucy."
