The Oscars presenter made light of the fact the veteran actor, an infamous womaniser, and Faye Dunaway mistakenly read out 'La La Land' as the winner of Best Picture, which was really won by 'Moonlight', at Sunday's (26.02.17) ceremony, but admitted he is unsure what actually happened.

He quipped: "Warren Beatty has had so much sex he can't think about it right. This is a guy who probably never had to sign anything, he just has people do that for him."

But Jimmy confirmed the pair had been handed an envelope which stated 'Emma Stone - 'La La Land'' - seemingly a duplicate of the Best Actress in a Leading Role winner reveal - prompting the confusion.

Speaking during the ABC Aftershow, he said: "I don't know the whole story -- there's a couple things I do know though. The envelope Warren Beatty was holding said best actress. That I do know.

"He was confused because the card, which he showed to be me by the way, said, 'Emma Stone, La La Land.' We thought he was being coy and cute and milking it, but in reality he was as perplexed as anybody."

And the 'Jimmy Kimmel Live!' presenter admitted he never expected the ending of the prestigious ceremony to be so dramatic but that's just what he loves about live television.

He added: "You know, you do a talk show every night and you thrive on these moments. This is exactly what you want."

Emma previously insisted she was still clutching her Best Actress in a Leading Role winner's card when the Best Picture announcement was made.

She said: "I was holding my Best Actress in a Leading Role card that entire time.

"So whatever story - I don't mean to start stuff - but whatever story that was, I had the card. So, I'm not sure what happened."
