Rihanna leaving a nightclub in London

Rihanna and Drake aren't officially girlfriend and boyfriend.

The duo have been dating exclusively for a number of weeks and were photographed holding hands in London earlier this week, but reportedly haven't put a label on their relationship yet.

A source close to the 26-year-old beauty told HollywoodLife.com that she is very "happy" that the 'Hold On, We're Going Home' hitmaker, 27, "belongs to her" but they are in no rush to discuss their romance.

The insider explained: "She's just happy to be in his presence and wanted by him.

"Nothing is official in terms of their relationship but they're still dating and sleeping with each other exclusively. You'll see them out and about, holding hands and being all lovey dovey these days. It's no secret that he belongs to her and she to him but as far as them coming out and being like, 'Oh hey, look at us, it's official,' who knows when that's going to happen?"

A source previously claimed the 'Stay' hitmaker is besotted with the Canadian star because he treats her so much better than her ex-boyfriend Chris Brown, and they have been headed towards a relationship for a long while following their brief fling in 2009.

The friend said: "Rihanna and Drake really have this chemistry and vibe with one another and that's something they can't explain. They're both kind of infatuated with each other."
