The 52-year-old presenter judged 'America's Got Talent' alongside Sharon, 65, from 2007 to 2011 and he has now lifted the lid on the ''worst experience'' he had whilst working with her.
Revealing the mid-air incident on UK TV show 'Loose Women' on Monday (27.11.17), on which Sharon was also a guest, Piers joked: ''Perhaps the worst experience ... I'm still traumatised by this. I was on a private jet from Chicago to LA with all the stars of the show. Sharon has hit the red wine, and I go to sleep. But I was woken up at 2am with a sort of kerfuffle. I look up and all I can see is this blur in front of me and I realise it is Sharon's naked breast and I'm being filmed. I've never felt so traumatised.''
Journalist Piers also revealed the first time he and Sharon met she throttled him and began to ''strangle'' him to death.
He said: ''I get a call saying 'look we've had a change of judges, Sharon Osbourne is joining the show.' I thought 'oh that could be awkward' as I'd written some not entirely complimentary things about Sharon. Anyway we meet for a dinner with NBC and all their executives, Jerry Springer, who was going to be the new host, which was just as well given what happened. Anyway dinner went OK, Ozzy [Osbourne] was there and we were getting on quite well, then I said something a little bit confrontational and then Sharon responded. Sharon had run up behind me ... all the top executives were there. She runs up behind me and begins to strangle me to death. It wasn't funny. She was literally throttling me. Ozzy was trying to pull her off. Eventually Jerry Springer had to literally pull her off me. I got back to my hotel room and take a sleeping pill to try and get over the whole thing.''
Piers later received a phone call from Ozzy who forced his wife to apologise to him.
