He is notoriously private when it comes to his personal life but Lewis Hamilton briefly let his guard down at the MTV VMAs 2015 to finally answer the question fans have been dying to know. Is he dating Rihanna?

The 30-year-old Formula one ace was first linked to RiRi at the Met Gala in New York back in May, when they sat together at the after-party. Earlier in August they were spotted enjoying a day of watersports in her native Barbados. They continued to send tongues wagging after being spotted partying in the Big Apple at the 1Oak nightclub in New York on 11 August.

"They've had a flirtation for years and have always fancied each other, but since May this year they've been talking a lot. Finally their schedules allowed them to spend a weekend in the same part of the world and they made the most of it," a source added.

Speaking to E! News at the VMA's, the 30-year-old addressed the romance rumours, without actually giving too much away. "You know, I've known Ri for a long time", he said. "We've been friends for a while. We get to hang out every now and again...' Oh. Well that didn't give much away, did it?!"

Although Hamilton is keeping tight-lipped about the status of their relationship, an insider said that he's smitten. "[He] thinks she is not only sexy but incredibly funny, although he knows she has a reputation as a heartbreaker," the source added.

In other words, watch this space.

Meanwhile, celebrity gossip website, Urban Islandz, reports that the Diamonds hitmaker's ex boyfriend Chris Brown is jealous and has even confronted her about the relationship rumours.

"He (Chris Brown) asked her what is the status of their relationship and she told him that they are just friends hanging out," a source said.

"She [Rihanna] sense that there are some jealousy [sic] and playfully asked him if he is jealous and his response was no, but she knows him very well and know when he is being jealous or not. She really likes to rub it in that this is what you lost, but it's good that they are maintaining a healthy friendship," the insider added.
