The pair have fun at Mayfair's Loulou bar
The Duke and Duchess of Cambridge arrived at the bar – joining a party for one of their friends – at around 10pm and left quietly through the back door just over two hours later.
But Pippa, 29, chose to stay with pals and made her way home much later at 2.30am.
Kate and Wills‘ evening out reunited them after they spent the day apart.
William had attended the funeral of his childhood nanny Olga Powell in Essex and the Duchess visited Newcastle for a series of solo public appearances.
Kate told crowds at the city’s Civic Centre that she’d ‘missed’ her husband on the trip.
