Gabrielle Union claims Simon Cowell's smoking on the set of 'America's Got Talent' made her ill

Gabrielle alleges that the smoke made her sick for two months and her illness, in turn, upset co-star Howie Mandel, who is a self-confessed germaphobe.

She told Variety: "I couldn't escape. I ended up staying sick for two months straight. It was a cold that lingered, and turned into bronchitis, because I couldn't shake it. It impacted my voice, which affects my ability to do my job.

"It was challenging to tend to my illness without being made to feel like I'm responsible for my own sickness. It put me in a position from day one where I felt othered. I felt isolated. I felt singled out as being difficult, when I'm asking for basic laws to be followed. I want to come to work and be healthy and safe and listened to."

A spokesperson for Simon said: "When he was directly informed of the smoking complaint during the first couple of days of the season, he immediately changed his behaviour and the issue was never raised again."

Speaking previously about quitting smoking, Simon - who used to puff on 80 cigarettes a day before cutting back in 2016 and taking up vaping - said: "If I tried to cut out cigarettes completely, I would have a real problem: too boring."

Meanwhile, Gabrielle - who is married to NBA player Dwyane Wade - also called for Jay Leno to be reported over an offensive joke he made on the show and said she flagged one contestant's act, which she felt was problematic.

She said: "If I can't speak out with the privilege that I have, and the benefits that my husband and I have, what is the point of making it? What is the point of having a seat at the table and protecting your privilege when you're not doing s**t to help other people?"

Fremantle, Syco and NBC told Variety in a joint response that they "immediately engaged an outside investigator who conducted more than 30 interviews to review the issues raised by Ms. Union. While the investigation has demonstrated an overall culture of diversity, it has also highlighted some areas in which reporting processes could be improved".
