An embarrassed Bridget Jones tried to keep her big knickers hidden during a sexy encounter in the first movie of the popular series.
But in the latest instalment being filmed in London, her bohemian neighbour flaunts her bloomer-like dacks, as this picture shows.
West Australian actress Isla Fisher was seen last week filming scenes as the neighbour wearing a large pair of cream silk pants under a black sheer maxi skirt, a matching vest top and orange velvet coat.
The scenes for Bridget Jones: Mad About The Boy — the fourth and final film in the series — were shot on set in Hampstead, north London.
In an infamous scene in Bridget Jones’s Diary in 2001, Bridget, played by Renee Zellweger, cringes and tries to cover up when Hugh Grant’s character Daniel Cleaver discovers her knickers as the pair get frisky.
Fisher, 48, who split from her comedian husband Sacha Baron Cohen earlier this year, will be seen along with Zellweger and Grant reprising their roles in the new film next year.
Earlier this month she was spotted running amok on the set, wearing furry slippers between takes.
She was seen sporting a voluminous golden frock and forest green coat framed by a sparkly belt buckle and flowing pendant, swapping the slippers for laced heels as she got into character.
Grinning from ear to ear, Fisher appeared upbeat and even wielded a large red water gun as she played gleefully with children while filming a scene.
However, the fun was short-lived, as the fourth instalment of the successful franchise was reportedly “thrown into chaos” when an unnamed cast member suffered a broken bone and was taken to hospital.
