With today marking their very first Valentine's Day as a couple, Sofia, 19, celebrated the momentous occasion by sharing a sweet photo with her 34-year-old beau on Instagram.
She captioned the black-and-white throwback pic, "Happy Valentines babe."
In the shot, which was taken last October during the pair's PDA-filled vacation to Venice, Italy, the duo look head-over-heels while cuddling in sunglasses. Later in the day, she showed off a bouquet of roses on Snapchat from the reality star.
And while they have recently taken their love public via social media, this is a relatively new occurrence for the couple. During Sunday night's episode of Keeping up with the Kardashians, Scott revealed that he was keeping his relationship with Sofia a secret out of respect for his ex, Kourtney Kardashian.
