Pippa - who got engaged to James Matthews in July - looked in relaxed mood as she headed out with her mum on her special day.

While James was nowhere to be seen during the stroll, the happy couple are likely to have spent time with each other last night.

Her £200,000 engagement ring was certainly on show for their walk.

Pippa and James are expected to tie the knot next year, and Carole is said to have been the "mastermind" behind the hedge fund manager popping the question.

A source recently said: "This is something she has hoped for quite some time. She appears to be something of a mastermind in making this happen."

Before asking Pippa to marry him, James is said to have approached her father Michael Middleton, 67, and asked for his daughter's hand in marriage in the traditional way.

A source said: "James is a traditionalist and very much wanted to do things properly. That meant getting his future father-in-law's consent. Mike and Carole are very happy. They like James and they are sure he will make Pippa very happy.

"He worked very hard from an early age. He's a smart chap but also the sort of bloke you would be proud to call a friend He made a huge amount of cash from hedge funds and some more from the London property market. We're talking millions here and you don't do that by the age of 40 unless you are a sharp cookie. And James is very bright."
