LIVE FROM THE RED CARPET HOSTS' MOST MEMORABLE MOMENTS
1 When English comedian Sacha Baron Cohen dumped "Bisquick" on Ryan Seacrest
At the 2012 Oscars, The Dictator actor tipped an urn filled with "Kim Jong Il's ashes" on Seacrest as a prank.
"I've always wanted Bisquick (what Seacrest calls the ashes) on my lapel. It was a bit desperate but, sure, it was a great moment," said Seacrest.
2 When Maroon 5 singer Adam Levine got mad at Giuliana Rancic
She recalled: "Sometimes people are not in the mood to get personal. I once asked him one too many questions about his romantic life at the Golden Globes in 2012, and you could tell he was having none of it.
"Months later, I arrived in Mexico, saw him and asked if he wanted to be escorted together to the front of the customs queue with me. He then apologised for that day and said he was 'a little off' and 'not in a good mood', which was understandable and sweet of him."
3 When US actress Jennifer Lawrence had "armpit vagina"
Rancic said: "Sometimes there are moments that are headline-worthy, like when I told Jennifer Lawrence last year that she looked gorgeous in her Dior gown at the Screen Actors Guild Awards. She looked at the live monitor and went, 'I know I have armpit fat, it's okay. Armpit vaginas, it's awful'. It trended worldwide within 10 minutes."
4 When Giuliana Rancic "lei-d" US actor George Clooney
At the Screen Actors Guild Awards in 2012, Rancic came equipped with a lei (garland) specially for her favourite star.
"I said, 'So George, I've always wanted to 'lei' you' before putting one around his neck. So I got to 'lay' George on the red carpet," she said.
Clooney's equally jokey reply to her that night?
"I've now been lei-d, I can't say how happy I am."
