The actress stunned fans in her figure-hugging dress and elaborate hat, which was reminiscent of Audrey Hepburn, who originally starred as the cockney flower girl who transforms into a woman of poise and polish.
Captioning the photo, Martine penned: "My Freddie & I Played to perfection by the wonderful Mark Umbers in the National Theatre run of MY Fair Lady. 'It was the gin that did her in!'"

Martine is fond of sharing throwbacks with her Instagram followers. Back in May, she posted an incredible modelling photo from when she was just 11 in honour of her 46th birthday.

Complaining about the unsavoury weather at the time, she penned: "Erm… Exsqueeze me guys… But where's the sun gone?! Me and my 11 year old self (modelling for Tammy girl) are a bit in shock - I thought it was meant to be lovely all week & it's my birthday on Saturday!"
The sweet black-and-white snapshot showed Martine posing in a Sylvester the Cat jumper, teamed with a short black skirt and tights. Her natural curls were pulled up into two buns and she struck a playful pose for the camera.
