Pretty Little Liars' Shay Mitchell suffers on-air wardrobe malfunction, needs emergency sewing

Pretty Little Liars star Shay Mitchell had a pretty little problem to deal with as she guest-hosted US morning show Live! With Kelly and Michael. And no, it wasn't just her nerves!

The 29-year-old's dress strap snapped during a commercial break, prompting swift action from a team of professionals whose sole purpose in life is to prevent excessive overexposure. They swoop in with military precision, because it's serious business, people.

Of course, the show posted the whole dress debacle on Instagram and Snapchat with the caption: "A little #commercialbreak sewing after a wardrobe malfunction. No biggie."

And Shay had a sense of humour about it too, as you can see from her Instagram LOL below.

FYI, we'll see Shay up on the big screen soon in Jennifer Aniston and Julia Roberts' new comedy Mother's Day. Yes, the one where Julia has a hideous Anna Wintour-style wig.
