The pair first sparked romance rumors in the summer of 2017 when the pair were spotted on a yacht together with friends during the Cannes Film Festival.

'Scott and Sofia are the type of couple that constantly split up and get back together,' the source said. 'It's all very dramatic, and then all good again.'

In a since-deleted tweet around the time of their boating adventure, Lionel Richie's daughter wrote: 'Just so everyone can get their panties out of their asses, Scott and I are just homies #relax.'

E! News reported just weeks after that the pair were spotted arm-in-arm while leaving a romantic dinner at Nobu in Malibu.

Shortly after she took to Twitter saying: 'The last time I'm gonna say it. Scott and I are just friends. I'm single and focused on friends, family and work. #againrelax.'

They finally made things official online in September 2017 with his-and-hers posts from a sunny holiday in Miami Beach.

And while Scott found fame dating Kourtney Kardashian for nearly 10 years, he was hesitant to invite Sofia on a trip while filming the family's famous show, Keeping Up With The Kardashians.

'I definitely think this trip, out of the other trips we’ve been on, has a little bit more pressure because the truth of the matter is, there are camera crews everywhere, tons of people walking around that Kourtney and I have known for over 10 years,' he said.

Kourtney and Scott dated for years before finally calling it quits on their relationship in 2015; they share three children together: Mason, Penelope and Reign.

'Sofia has never really done anything like this before. It's hard,' he said during an episode in 2019. 'I don't want her to feel out of place, I don't want her to feel like she's not as comfortable as I am. I'm just trying to be cautious of everyone's feelings.'
