Awks: Emma Watson has revealed she hasn’t always been a smooth talker, and got herself into a rather awkward situation a few years ago

Blushing as she recounted the incident, Emma remembered how during their previous interview she mistook Fallon for Kimmel, and opened their chat with:’I love that Halloween candy thing that you do.’

However she soon realise the skit she was referring to- a scene where parents pretend to eat their children’s sweets, was in fact from Fallon show.

‘I died inside,’ she said. ‘You could tell that I was dying inside and you were like, ‘It’s okay, honey. If you want to go out and start again, we can do it again’.

Meanwhile she also revealed that she went to ‘princess boot camp’ to prepare for Beauty And The Beast during a chat show appearance Thursday.

The actress was asked about her preparations for the Disney blockbuster by The Tonight Show host Jimmy Fallon.

‘I did princess boot camp for three months. It was fun,’ Watson said while appearing on the show in a sleeveless white blouse and black trousers.

‘I got to ride a horse, I got to learn to waltz and then I had singing lessons and then rehearsals,’ she said.

‘It was cool,’ Watson added.

Fallon asked if she could still waltz and Watson humbly replied, ‘I could stumble my way through something reasonable.’

Beauty And The Beast premiered in February in London and was released in the US in March.

The romantic fantasy film has grossed more than $1 billion at the worldwide box office and is the highest-grossing film of the year.

‘It’s crazy, crazy,’ Watson said of its box office performance.

‘It just means people love the film, which is so awesome,’ she added.

Red-faced: Fallon pointed out that she was making reference to his late-night rival instead and replied to an embarrassed Emma: ‘That’s Jimmy Kimmel…’

Moving on: Despite the blunder, the pair seem to have formed a friendship and couldn’t stop laughing as they recalled how they first met

The actress also laughed about her previous appearance on a chat show with Fallon.

Fallon, 42, explained that they first met years ago when he was hosting Late Night With Jimmy Fallon and Emma immediately complimented him for his Halloween candy prank segments.

‘That’s Jimmy Kimmel,’ Fallon recalled telling her in reference to his late-night rival.
