The former couple - who have three children, Mason, six, Penelope, who turns four on Friday (08.07.16), and Reign, 18 months, together - may have split up last summer after nine years together, but the 33-year-old star still felt it was important to be with his ex-partner on her special day in April.
In a preview for an upcoming episode of 'Keeping Up With the Kardashians', Scott told Kourtney's mother Kris Jenner: "Kourtney and I have spent every birthday together, between mine and hers, for the past 10 years.
"And her birthday's coming up. Do I just say, like, screw it and just fly to Iceland and surprise her?
"Let's say if, in a year from now or 10 years from now, we work things out - I would've hated to have missed a birthday."
However, Kris was unconvinced by Scott's suggestion.
She said: "The thing that I hear her say is that she just wants you to be a good person and a great dad and to do it first for yourself and then for your kids and then for her."
And the 60-year-old matriarch went on to recommend Scott focused his efforts on his children.
She said: "[Concentrate on being] that fun dad and that responsible dad that she's always praying you will turn into."
He glumly replied: "Yeah, I don't know. It's hard sometimes when you've had all these memories and then they are stopping one by one."
Scott recently joined the Kardashian family on a holiday to Cuba and he admitted he was on his best behaviour so he could impress his former love.
He said on the show: "One of the biggest issues between Kourtney and I is me drinking. I get overly emotional when I drink and I just want her to see that I can keep it together."
And his plan seemed to work as Kourtney, 37, was very impressed by Scott.
Speaking to sister Kim Kardashian West, she revealed: "I'm really glad he came, he's been so good. He has been fine. I'm glad that he could be here.
"It was a great decision to have Scott on the trip and it's great for him to know that he's always going to be a part of the family."
