Talk about a pair.

Michelle Obama and Duchess Meghan met in London during a stop on the former first lady's book tour for her new memoir "Becoming," according to reports in the Evening Standard and Harper's Bazaar.

The Duchess "privately attended" a discussion between Obama and writer Chimamanda Ngozi at London's Southbank Centre Monday night, Kensington Palace confirmed to USA TODAY.

In a recent interview with Good Housekeeping , Obama offered up her advice to Duchess Meghan, based on her own experiences as a private citizen who was thrust into the public spotlight.

“Like me, Meghan probably never dreamt that she’d have a life like this, and the pressure you feel – from yourself and from others – can sometimes feel like a lot,” she said. "So my biggest piece of advice would be to take some time and don’t be in a hurry to do anything."

Duchess Meghan's husband Prince Harry is historically close with former President Barack Obama, hanging out with him and Joe Biden at the 2017 Invictus Games and interviewing him for a BBC radio story that broadcast later that year, with Obama joking that he was a fan of "Suits," the USA drama that famously starred Duchess Meghan during her acting days.

Obama also congratulated Harry and Meghan on getting engaged last year – with the couple recently spending the anniversary of their engagement apart –and wrote in a tweet, "Michelle and I are delighted to congratulate Prince Harry and Meghan Markle on their engagement. We wish you a lifetime of joy and happiness together."
