Pippa and James were first spotted earlier this month, enjoying a cosy evening meal at Queen's Club tennis centre in West London.

And in the last fortnight, the couple have also visited Hakkasan, where onlookers said they sat away from prying eyes in a 'secluded booth,' and were 'openly flirting' with each other.

'They were deep in conversation ad only had eyes for each other. Pippa was all smiles and kept giggling,' one diner revealed.

'They stayed for nearly three houses and didn't seem to want the meal to end.'

Afterwards, Pippa and James were spotted getting into a taxi together, Pippa dressed in a chic black dress, lace jacket and black suede heels.

Friends of the younger Middleton sister say she is 'quite taken' with her latest love interested, but 'wants to take things slowly at first'.

'Pippa is quite taken with James. She wants to take things slowly at first but she she is ready for a full-time man in her life again,' a fried of the royal bridesmaid told the Sunday Mirror.

Pippa split with long-term love Alex Loudon last year, and has since been linked to heir to the Duke of Northumberland, George Percy.
