With temperatures soaring close to 40C in Los Angeles yesterday afternoon, stars struggled to cope on the Emmys red carpet.

Heavy make-up and floor-sweeping gowns are hardly perfect hot weather attire, and the sizzling weather meant a lot of attendees were suffering. But things got too much for one actress in particular when she came close to collapsing during an E!'s live red carpet broadcast.

Olivia Culpo was on air with hosts Giuliana Rancic, Ross Matthews and Brad Goreski when she fell to her knees behind a podium.

She could be seen with her head between her legs as the other stars rushed to help her.

In another red carpet link-up later on, Giuliana was quick to reassure viewers that the former Miss USA was doing fine. "She got a little overheated at the end there, she's okay," she explained.

Olivia also took to Twitter after her fright, posting a picture of herself in a wheelchair being pushed through the theatre's main lobby.

"OMG it is SO HOT out here. Literally just almost passed out #Emmys2015 #ERedCarpet," she wrote, adding, "@GiulianaRancic @helloross @mrbradgoreski its ok I know u would have caught me."

Though there were no other fainting incidents, other stars were certainly showing signs of overheating.

Dancing With The Stars host Mario Lopez was drenched in sweat under his suit jacket, but he didn't mind showing off.

A pregnant Cat Deeley wisely came along with a portable fan:

And Amy Schumer followed suit too, being sure to keep cool in her custom made Zac Posen gown:

You'd never have this problem at the IFTAs, that's for sure.
