Rihanna crossed paths with rumoured beau Pharrell Williams in London today.

The singer checked into the Soho Hotel where the N.E.R.D frontman has been bedding down during his stay in the capital.

Pharrell - who has been linked to the Umbrella star following her split from Chris Brown - was seen leaving the hotel an hour later.

Earlier Rihanna had shown off her punk-inspired haircut as she touched down at Heathrow airport.

The singer – who is known for her edgy 'dos – was snapped wearing her hair piled high on her head to reveal a shaved back 'n' sides.

The previous day she stepped out for a dinner date at an Italian restaurant in New York clad in a sheer top with her stripy bra showing underneath.

After lunch she had an appointment at the opticians.

We hope her 'experimental' hairstyles of late are intentional and nothing to do with her dodgy eyesight.
