• Scott Disick and Sofia Richie dated for over three years before calling it quits.
• From the first time they were spotted together in 2017, the reality star and the model's relationship polarized fans due to their 15-year age gap.
• Disick and Richie dove headfirst into their romance with trips to Italy, Greece, Mexico, and Saudi Arabia.
• They took a break in May 2020 following Disick's rehab stint before deciding to end their relationship.
• Here's a timeline of the former couple's controversial relationship.

Scott Disick shocked fans when he was first photographed getting handsy with Sofia Richie in 2017.

Because the 34-year-old reality star dated Kourtney Kardashian for 10 years and shares three children with her, the 21-year-old model, a longtime friend of Kardashian's half-sister Kylie Jenner, was a contentious selection.

There was also the 15-year age gap between them, which led many people to brush off the notorious bachelor's behavior as a mere flirtation. What followed, to the surprise of many, was a three-year relationship — far from drama-free, but endearing in its own unique way.

After Disick briefly returned to rehab in 2020 to work through "past traumas," the couple called it quits but reportedly remains in touch.

From jet-setting trips around the world to their awkward cameos on E!'s "Keeping Up With the Kardashians," here's a timeline of Richie and Disick's relationship.
