We all have seen how Kourtney Kardashian's relationship with her ex-partner Scott Disick has gone from romantic-crazy to severely complicated over the years. However, despite their on-again off-again relationship over the years and their final split in 2015, they have always been civil to each other and to their three kids.

Although they have moved on to date other people, they have always remained close, in which people have made speculations about.

Some time this month, Scott confirmed his relationship with Lionel Richie's daughter, Sofia Richie, and he's been very open about it, especially to Kourtney.

And the "Keeping Up With The Kardashians" star seems to have no problem with it!

Scott and Kourtney's Relationship Timeline

Scott and Kourtney met at a house party thrown by "Girls Gone Wild" in 2006. Not long after that, they started dating just when "Keeping Up With The Kardashians" first aired in 2007 -- a time when the two of them were a hot item. 

In the show, it featured Kourtney and Scott's relationship, including their arguments about the latter's bad partying habits and a couple of pregnancy scare. However, both of them got through it, and they welcome three beautiful children: Mason Dash, Penelope Scotland, and Reign Aston Disick.

Throughout their public relationship, Kourtney and Scott had a lot of issues going on that time, especially when Scott had depression due to the death of both of his parents. 

The ex-couple finally ended their on-again, off-again relationship for good just months after their third child, Reign, was born in 2014. However, they remained civil in each others' lives. Scott was still considered as a part of their family and appears on their reality show and in some of their family vacations.

Scott, Kourtney, and Sofia Richie

Scott and Kourtney went on dating other people after their breakup. Before officially dating her current model boyfriend -- Younes Bendjima -- Kourtney was even rumored to have a short fling with singer Justin Bieber (and no one seems to have a problem with it).

However, when it came to Scott's dating status, people have thrown a lot of speculations and hate towards him, especially when he and Sofia Richie started going out. Scott started following Sofia in early 2017, and a lot of people expected the romance won't last because of Scott's dating attitude.

Surprisingly though, Scott and Sofia are still together and are stronger than ever.

Also, one thing why Scott and Sofia's relationship are being judged is because of their age difference. When they met, Scott was 34 and Sofia was only 19. The age difference drew a lot of hate from people, with some saying Disick won't take her seriously.

Despite everything, people were in shock to see that Kourtney has always been supportive of her ex-husband's new found love. In KUWTK, Sofia has also joined one of their family vacations.

Everything seems to be going well between Kourtney and Scott, so there's nothing to worry about.
