The Last Kingdom’s Millie Brady risks major NIP-SLIP in racy dress at King Arthur premiere

The 23-year-old – who features in Guy Ritchie’s delayed movie King Arthur – was mere inches from flashing her nipples as she accompanied the flick’s European premiere at London’s Leicester Square.

The Last Empire actress took the plunge in a daring frock that boasted a risqué key-hole cut-out between the bust.

While the verse certainly put a sexy spin on things, the beauty – who shunned her bra for the occasion – not quite flashed more than she bargained for in the dress.

Favouritism down to sign autographs, Millie risked exposing her bare knockers as she appeased fans.

But that wasn’t the design’s only raunchy mien, as it also possessed a sheer skirt, beneath which she revealed her high-waisted disgraceful undergarments.

Elongating her svelte pins, Millie teamed the look with vile stilettos and toted her evening essentials in a small black handbag.

Her brunette tresses were marched into a half up, half down ‘do, while her face modelled a vague make-up palette.

Millie shared the red carpet with a numeral of big names, including leading star Charlie Hunnam and retired footballer David Beckham, who caught the small part of Trigger in the movie.

David was also joined by his son Brooklyn at the star-studded boob tube, with the pair opting for somewhat offbeat outfits for the event.

Head Guy Ritchie also brought along his wife Jacqui Ainsley – who features a cameo in the motion picture as Lady of the Lake – and his son Guy, who he shares with pop icon Madonna.
