Kate Middleton and Prince Harry used to be very close. But there are no reports about the two ever going out for a drink together before the Duchess of Cambridge married Prince William.

Even though the two royals never went to bars together, it seems that Prince William’s wife finally benefited from the Duke of Sussex’s hard-partying days when he was still a bachelor. Charlotte Griffiths, a journalist for Daily Mail, revealed the reason why.

She said that the mom of three attended an acquaintance party with the other moms who sent their kids to Thomas’s Battersea for the school year a few weeks ago. The group went to Hollywood Arms, a low-key bar that is a favorite among its regulars.

Middleton reportedly entered the venue via a secret door that was installed especially for Meghan Markle’s husband. Since Prince Harry used to love to party and drink a lot as a bachelor, the venue installed a secret entrance for him so that he could go in and out of the bar without being photographed.

And just a few weeks ago, the Duchess of Cambridge also received the same protection. She was able to arrive and leave the venue without being photographed.

The future Queen reportedly enjoyed a few drinks, and she also relaxed in the company of her friends. They stayed inside the private salon called Boulevard Bar.

“It seems to me that the Duchess is showing all the signs of being as laid back as the Queen when she is off duty. It’s quite a feat for a senior Royal to avoid making a song and dance in public… particularly when they are attending a song and dance!” Griffiths said.

Meanwhile, Princess Charlotte joined her older brother, Prince George, at Thomas’s Battersea this school year. Even though Middleton is not technically a new mom at the school, she’s a newcomer together with the parents of Princess Charlotte’s classmates.
