Scott Disick and Sofia Richie have been dating for so long that Sofia's had multiple hair colors during their relationship. These days, she's a brunette.
But Wednesday was the couple's first ever Valentine's Day together.
And they didn't let the holiday pass without marking the occasion.
For starters, Sofia Richie shared this black-and-white throwback photo.
Even without color, you can tell that Sofia was blonde at the time that it was taken.
This particular throwback was taken during Scott and Sofia's sexy Italian vacation.
Which was, for those of you keeping track, after their big debut on their sexy vacation to Mexico.
Sofia Richie had more to share.
In her story, Sofia gave fans and followers a glimpse of what appears to be a small army of bright red roses that Scott had given her.
Obviously, some things are private.
Scott Disick may share his girlfriend's butt with fans from time to time, but Valentine's Day is special.
Even for celebrity couples.
But just look at how happy Sofia looks right here in this image:
That's so sweet!
Of course, initially, Scott and Sofia were fairly discreet about their comings and goings.
In this past episode of Keeping Up With The Kardashians, the storyline finally reached the point where Scott Disick is dating Sofia Richie.
Obviously, the episode was filmed months and months before airing.
In it, Scott revealed that he was keeping the relationship on the down-low out of respect for Kourtney.
Perhaps he was trying to atone for how humiliated she must have felt while he drank and boinked his way around all summer in 2017, running through 19-year-old model after 19-year-old model until he finally settled on Sofia.
If he really cared about Kourtney's feelings, maybe he would have resisted his self-destructive impulses and not
But that's in the past, and Scott seems to be much healthier these days. At least, when compared to how he was over the summer when friends were reportedly concerned that he might drink himself to death.
And it was thoughtful of him, if definitely too late, to be so concerned about Kourtney's feelings.
We have to wonder how Scott Disick feels about Lionel Richie being scared to death that young Sofia Richie is dating the much older womanizer.
Maybe Scott has found a way to smooth things out, or maybe Sofia managed to assuage her father's worries. It's been months.
There's no telling how long Scott's relationship with Sofia will last.
It could be that they'll wake up one day and the honeymoon phase will be over and Sofia either find an age-appropriate hot model or a new older millionaire to spoil her and Scott will find a new woman who's young enough to think that he's cool and mature.
But you know what? Kourtney's relationship with Younes Bendjima no longer looks like a "boy toy" situation, and he's a younger, hot model, too.
It could be that Scott and Sofia are in for the long haul.
Sometimes, relationships that look like flings to outsiders can last a lot longer than anyone would imagine.
