Scott Disick and Sofia Richie filmed kissing

They've been romantically linked for months and now it seesm Scott Disick and Sofia Richie are ready to go public after they were filmed kissing.

Spotted together at a restaurant over the weekend, the pair appeared to be celebrating a special occasion as they locked lips in front of friends and a dessert plate that had "Congratulations Scott and Sophia [sic]!" written in chocolate frosting. Watch the couple smooch in the clip above.

Hm, could Scott and Sofia's romance finally be official?

It certainly seems sparks are flying between the two despite the age gap, with father-of-three Scott turning 34 in May, while Sofia recently celebrated her 19th birthday back in August.

In the footage, Scott and Sofia pucker up while they are cheered on by a group of friends who have joined them for dinner.

Scott, who shares three children with ex Kourtney Kardashian, has been linked to Lionel Richie's daughter this year, with Sofia taking to Twitter to deny they were anything more than friends earlier this year.

"Just so everyone can get their panties out of their asses, Scott and I are just homies. #Relax," she tweeted in May.

After their PDA, Scott appeared to make their relationship "Instagram official", sharing a snap of himself nuzzling into Sofia's neck to his Instagram story.

Meanwhile a source tells Us Weekly Scott's baby mamma Kourt isn't shocked by her ex's romance with a much younger woman.

"Kourtney thinks this fling with Sofia is a little weird, but nothing shocks her anymore. Kourtney just wants Scott to be his old self," the insider told the outlet. "She shares three kids with him, so she'll always want the best for him and will always make sure he's happy."
