CANNES 2019 guest and ex of Leonardo DiCaprio, Toni Garrn, suffered not one but two wardrobe malfunctions on the red carpet at the Cannes Film Festival last night.

Toni Garrn suffered two embarrassing wardrobe malfunctions on the red carpet at the Cannes Film Festival last night.

The 26-year-old model turned heads in a stunning custom-made gown when she appeared on the steps at the premiere screening of A Hidden Life.

The Calvin Klein beauty, who previously dated Hollywood actor Leonardo DiCaprio,  flashed a bit more then intended in a specially made white dress, which featured a low-cut corset-style bodice and long skirt.

The Grecian inspired design drew attention to her long legs with a daring thigh-high slit on one side and swathes of fabric which gathered at hip on the other side.

Toni, who has also modelled for Prada and Versace, added some sparkle to her outfit with a pair of diamond earrings and a set of stunning statement necklaces.

She teamed her dress with metallic silver heels and dark nail varnish on her fingers and toes.

Wearing her hair in a sleek ponytail she enhanced her natural beauty with smokey eyeshadow and light pink lipstick.

While smiling for the cameras during the festival in her show-stopping ensemble, Toni swished her skirt a bit too enthusiastically and flashed her bare bottom for all to see.

She later revealed her knickers while while striking a pose for the well-dressed photographers at the glitzy event.

The Victoria’s Secret star took to social media following this morning to post some behind-the-scenes pictures from the annual event.

She shared the snaps with her 1.5 million Instagram followers, along with the caption:

“Getting ready with @vogueparis @messikajewelry for the “A Hidden Life” premiere once again, merci #MessikaJewelry made me feel like a princess.”
