Everyone knows that if there's a chance your ex is going to see you, then you have to have the ultimate outfit ready to go.
Away from the world you might be languishing in a tracksuit, crisps down your front and four-day unwashed hair matted in a bun, but when you do eventually step out blinking into the sunlight, then you're going to want to look the best you ever have. Especially if there's going to be a thousand flashbulbs trained on you.
And so if anyone's looking for a lesson in how to absolutely nail post-break up style, then just check out Lara Stone who made her first red carpet appearance since her reported split from husband David Walliams – and boy did she make the most of it.
Wearing a vintage (if 1994 can be called vintage) figure-hugging burnt gold dress by Versace, the model and mother-of-one sent photographers wild as she made her way into the Cannes premiere of Michael Caine's new movie, Youth. With her signature blonde hair piled up high on her head, Lara looked radiant as she posed and pouted for the cameras, working her Marilyn Monroe-esque curves.
And the 34-year-old Dutch model made sure her Instagram feed was full of envy-inducing snaps too, posting a picture of herself dancing like she just don't care on the red carpet, and sunning herself on a balcony.
We might not have the Versace dress, but we can definitely share some of Lara's attitude...
