Surprising their fans on the weekend, Scott Disick and Sofia Richie shared a picture on Instagram kissing each other. The duo made their romance official over a ‘congratulations’ cake as they enjoyed a night out with pals. The celebrations happened to continue on Saturday night as well when Scott Disick and Sofia Richie were spotted heading for a night out in Miami.

Scott Disick, 34, and model Sofia Richie have been flaunting their relationship by posting some adorable ‘love birds’ photos where we can see the couple kissing and hugging each other. While the reality star made things Instagram official by posting a sweet photo of him snuggling into Richie’s neck, the model too posted a similar photo on her Instagram account with the couple posing with beautiful scenery behind them.

The new couple were also spotted kissing while out to dinner, posing in front of a plate with the words ‘Congratulations Scott and Sophia.’

In May, the daughter of musician Lionel Richie was pictured cuddling up to Disick aboard a yacht in the south of France during the Cannes Film Festival. Since then, the pair has spent time together in Las Vegas and Malibu, despite Richie squashing relationship rumors at the end of May when she tweeted: “Just so everyone can get their panties out of their a–es, Scott and I are just homies.”

Disick was previously in an on-again-off-again relationship with Kourtney Kardashian, with whom he has three children — sons Mason, 7, and Reign, 2, and daughter Penelope, 5

Richie has previously dated Justin Bieber.
