Margot Robbie bounced back from a minor red carpet blunder to steal the show at the London premiere of The Legend of Tarzan.

The 25-year-old actress’ printed Miu Miu dress, which had an open back, sheer paneling, and a high center slit, came undone in the back while posing for pictures on the step-and-repeat.

Luckily for the Australian actress, her co-star Alexander Skarsgard was right behind her. He was seen assisting her with the back of the garment as she smiled appreciatively.

The stylish actor also stood in front of the 26-year-old actress as she adjusted her couture gown, which was fluttering in the breeze.

Margot was then spotted giving him a thank-you kiss on the cheek.

The 39-year-old actor was also spotted placing his arm around his co-star as they posed for photos.

Robbie, who plays Jane Clayton in David Yates’ film, has stated that she refused to drop weight for the part.

“It’s the 19th century (in the film) – if she’s got a bit of weight on her, it’s probably a good thing,” she told Australia’s TV Week.

“I’m not going to look thin just for the sake of it.”

The Legend Of Tarzan debuted in theaters on July 1, and in it, he and Margot share a hot kiss. Alexander is no stranger to great kisses. The actor bragged about his on-screen kiss with Ryan Kwanten, 39, during a sensual sex scene in Season 7 of True Blood. But Margot did not gush about her time with Leonardo DiCaprio, 41, describing their sex scene in Wolf of Wall Street as “so awkward!”

After this, Robbie will next be seen in Suicide Squad as Harley Quinn.
