Beyoncé was left seriously morto on the red carpet this week!

It takes a lot to faze Beyoncé but we reckon these recent events might have done it… almost!

The singer had just arrived at Tom Ford's AW15 womenswear catwalk show in Los Angeles on Friday when she had to make a quick dash backstage as her dress completely ripped along her backside.

Bey, who was apparently wearing a Tom Ford dress at the time, had to find a replacement from the stylists at the show. "Beyoncé had a huge wardrobe malfunction at the show," a source told Us Weekly. "Her dress ripped all the way up the back and she had to run backstage to find something else to wear." 

Given that a fashion show generally only lasts five to ten minutes, the Single Ladies singer missed most of the show and left husband Jay-Z sitting next to an empty seat. "The people back there couldn't get it [the dress] fixed in time, so she had to miss the show," the source continued. "Beyonce was so embarrassed, [but] she was really cool about it." 

Although the label missed out on a pretty lucrative photo op with Beyoncé in their new collection, the Tom Ford stylists were able to track down another dress which they fitted to Beyoncé in double quick time – a black crystal-embellished dress from the label's Spring 2014 collection.

"She was the latest person to the show and only caught the last few minutes of it," said the source.

Beyoncé and Jay-Z stayed around to pose for some photos afterwards – and we have to say the singer looks as chilled as anything despite her epic wardrobe malfunction!

What a professional!
