Jackie ‘O’ Henderson recently suffered a terrifying health scare after nearly collapsing from exhaustion on the set of The Masked Singer.

And the radio host, 46, looked rather tense as she took a break from filming at Sydney’s Carriageworks on Sunday.

Jackie, who filmed The Masked Singer that night and then woke up early to host her KIIS FM breakfast show, seemed tense as she paced the set with her phone while chatting on FaceTime.

On Wednesday, Jackie admitted that she recently nearly passed out on the set of the show due to lack of sleep and low blood sugar.

Speaking to the show’s host Osher Günsberg on her radio show, the blonde recalled, “You had to take 20 minutes because I was so close to passing out and I had to go backstage for 20 minutes.”

“I’ve never felt that in my life,” she confessed.

Osher admitted the cast and crew were “all very concerned” about Jackie’s health following her dizziness.

“I wasn’t going to say anything, of course, but we were all very concerned about you. That was a very long day, we had been on set for about 15 hours,” he begged.

Jackie apologized for delaying production due to her health fears and confessed, “I felt so bad, but it just came on.”

‘Do you know what it was? I had no sugar in my body at all and I had a black, tight dress that probably cut off my circulation. And with the lights and everything, I suddenly felt, ‘Woah! What’s coming over me?”

Despite her recent health scares, Jackie looked gorgeous on the set of the show this weekend.

With a dark spray tan, the mother of one shone in a black sequined mini dress and blue duster.

She added even more sparkle to her look with a pair of statement rhinestone earrings, and enhanced her complexion with a dramatic makeup look.
