Duchess Catherine reportedly had an evening out at the pub with fellow school mums

She apparently arrived through a secret door for a low-key entrance.

She may be the future Queen of England but you'll still be able to find her enjoying a drink or two down at the pub.
According to The Daily Mail, Duchess Catherine attended a 'meet and greet' drinks party in the Boulevard Bar, a private salon in the Hollywood Arms pub with other parents of new pupils attending Thomas's Battersea – four-year-old Princess Charlotte started at the school in September, while her older brother Prince George, six, has attended since 2017.
As per the publication, Kate arrived through a secret entrance, using a doorway near in the rear alley which meant she could make a low-key entrance and exit.
The Daily Mail says the pub was once a place to be seen for Chelsea socialites, however, is a lot more relaxed these days, and with only one royal protection officer in tow, it seems Kate was feeling pretty laid back herself.

The latest report comes as Duchess Catherine returns to royal duties following time-off spent with her three children, with the two eldest on half-term break.
Just a week before Halloween, the duchess was also spotted at a local Sainsbury close to the Cambridges' country home Anmer Hall, shopping for Halloween costumes with Charlotte and George.
According to The Mirror, mum-of-four Kathy Whittaker says she was at the store when another shopper pointed out that Kate was there, browsing the clothing section.
"She was with Charlotte and George looking at Halloween outfits but her bodyguard was kind of watching people with phones and telling them no pictures," Kathy told the publication, however she says Kate happily chatted away to some of the children in the store, asking them what they were going to dress up as for Halloween.
Kathy added the royal mum-of-three seemed "down to earth" and looked "beautiful as always".
"It was lovely to see her doing normal stuff that you and I do."

Earlier in the month The Duke and Duchess of Cambridge took their two oldest children to their first football match to cheer on Prince William's favourite team, Aston Villa.
The four of them were photographed enjoying the Aston Villa versus Norwich City Premier League game, with Aston Villa ultimately securing the win 5-1, and no one looked more excited than George.
Filmed celebrating an Aston Villa goal, Kensington Palace shared an adorable video of the six-year-old, sporting an Aston Villa t-shirt, jumping up and down in excitement.
