Oscar winner Cate Blanchett almost missed her category being called at the Oscars as she was at the bar with Julia Roberts.

The Australian star took home the Best Actress Award at this year's Oscars for her work in Woody Allen's Blue Jasmine and has revealed that she made it back to her seat just in time.

Speaking to E! News she explained, "The blessing and the curse of this is that [the award] happens at the arse end of the evening. You watch so many other extraordinary people go up there and you lose track of the fact that you're even nominated, and you get taken by surprise, and 'it's my turn'.

"I was with Julia Roberts at the bar for rather too long! And I just got back to my seat in time."
