The 26-year-old singer is reportedly smitten with the 28-year-old model and actress, who has three-year-old son Sire with the 'Candy Shop' hitmaker.

A source told E! News: "They really like each other. It's still new but they are exclusive and really like being around each other. It's a very carefree easy going relationship."

The 'Wiggle' hitmaker alluded to his new romance on Instagram on Friday (20.11.15), where he shared a recent photograph of him with his arm around Daphne while partying in London, with the caption: "#FlashBackFriday #London #GoodTimes @daphnejoy"

Jason split from Jordin Sparks in September 2014 after three years together and earlier this year he confessed he felt under pressure to marry her.

He said: "There was a lot of pressures of marriage. There was a lot of arguing and stuff like that just weighed on our relationship over time. When you stop having more good times than bad times, it's time to call it quits. It becomes something that is unhealthy."

He also said he wasn't ready to find another serious girlfriend, adding: "It's pretty clear that I'm not ready for that. I'm just not in the right space."
