The party took place in the pub’s Boulevard Bar – which costs around £2,500 to hire
Kate Middleton sneaked into a pub for a few drinks with other mum from her children’s school, reports say.
The Duchess of Cambridge, 37, enjoyed a secret “meet and greet” drinks party in Chelsea, the Mail on Sunday reports.
The party took place in the pub’s Boulevard Bar, which costs around £2,500 to hire for up to 80 people.
The news comes just a week after the Duchess was dubbed “relatable” after she was spotted shopping in her local Sainsbury’s .
Kate was seen walking in the Norfolk store, flanked by a bodyguard, with her children.
She donned a black outfit as gobsmacked shoppers watched the family head to the costumes aisle in the store in Hardwick.
Kate, whose bodyguard reportedly told shoppers not to take photos, apparently picked up Halloween costumes for George and Charlotte.
She then asked some children in the store what they were going to dress up for as Halloween.
The Duchess’s appearance in the Norfolk Sainsbury’s store suggests the family is staying at their 10-bedroom Anmer Hall in West Norfolk for the half-term holidays.
The royal home was a wedding present to Kate and Prince William from the Queen.
The event was held last month for parents of new pupils at the prestigious Thomas’s Battersea school – where just a term of schooling costs £6,000.
Mum-of-three Kate was reportedly able to sneak into the Hollywood Arms through a rear alleyway away from prying eyes – using a hidden doorway which had been specifically installed for Prince Harry.
