After a big break-up, most of us spend at least a few weeks buried under the duvet gorging on chocolate, hitting the town just a little bit too hard or indulging in a dramatic but ill-advised new hairdo.
But if Cressida Bonas has gone down any of these well-trodden post-split routes, she's certainly not showing it.
Ever since the 25-year-old drama graduate ended her two-year relationship with Prince Harry in April, her career seems to have flourished.
As is sometimes the way, it seems the split has been a tonic for Cressida in terms of her work and personal life and barely a week goes by without us hearing about some exciting new development for her.
Last night, she caught up with the royals including Sarah Ferguson and Princess Eugenie (a close personal friend who introduced her to Harry in 2012) at the Art Antiques Fair in London's Kensington.
The Leeds University graduate seemed fully at ease as she chatted with them and other guests, dressed in a black halter neck top and silver trousers (above, first and second image).
Cressida Bonas and Cara Delevingne are to appear in Tulip Fever together
Her appearance there comes just a few days after it was confirmed that she is to star alongside Brit model Cara Delevingne in 2015 period drama Tulip Fever.
The role represents Cressida's debut into the world of film, and, as it's a project involving Hollywood heavyweights Christoph Waltz and Harvey Weinstein, it's a considerable coup for the aspiring actress.
Based on the best-selling novel by Deborah Moggach, the movie will tell the story of an illicit affair between a painter and his wealthy muse.
Cressida is to take on the part of a wealthy society lady, with Cara and Daisy Lowe playing the artist's models.

Most recently, Cressida worked in a marketing job in Soho - where she commuted to her flat in Shepherd's Bush and Kensington Palace, for which she held a security pass to back in the days when she was dating Harry.
However, she's increasingly branched out into theatre over the past few months, with an appearance at Hay-on-Wye festival in May, where she played a singing Cockney with an obsession with health and safety regulations.
And now with the promise of a film role, her acting career looks set to burgeon even further.

Harry and Cressida ended their relationship in April just weeks after the pair appeared in public together (above) for the first time amid rumours of an engagement.
The pair had struggled to deal with the pressure of being in the spotlight, sources close to the royal confirmed.
"It's very sad that they have decided to split but this is a completely amicable separation and they are remaining the very best of friends," a friend of the couple told the Telegraph.
Insiders suggested Cressida wanted to time out to focus on her theatre marketing job.
"This gives Cressida the opportunity to focus on her career," a source said.
