Chris Brown has added further weight to rumours he is dating R&B star Rihanna by dropping hints about the romance to the audience at a recent gig.

The pair has been at the centre of speculation since they were photographed frolicking in a Jamaican swimming pool together last month.

Brown, who is in London for a series of live dates, was also snapped leaving a hotel with the Bajan beauty in the early hours of Saturday morning.

And now the 18-year-old singer has given the strongest clue yet that they are indeed a couple. He told the crowd at the Indigo O2 venue on Sunday night, "If I was the prince of R&B, then I would need a princess," and launching into a remix of Rihanna’s hit single Umbrella.
