Filmed following the Oscars luncheon, Anne appeared to be in a extremely high spirits as she arrived on set to talk with Zach.

Taking a seat on Zach's lap, a giddy Hathaway adorned him with kisses as she wrapped her arms around his neck.

Asked to move to her chair, Anne giggled as she said: 'So you're funny. You're really funny. I like you. Sorry.'

Galifianakis then questioned the Les Misérables star about her recent alcohol intake, to which she replied: 'No I didn't, you didn't know that, you can't prove it.'

Before being ushered away, when Zach told Anne he could smell liquor on her breath, the 30-year-old quipped: 'No that's my perfume, it's not that at all.' 

Anne also treated Zach to a few bars of Beyoncé's Best Thing I Never Had.

Another unfortunate interview sees Zach come face to face with hos former co-star Bradley Cooper in a less than harmonious reunion.

The union quickly turns sore when Zach hands Bradley a loser's speech he has composed which doesn't go down well.

Instantly angered, Cooper shouts: 'I just don't get it. This is the first time in my life that I'm a part of something and you know what that means to me to be a part of something, that's like my Achilles heel, I just want to be included.'

To which Galifianakis responds: 'Why don't you join the boys scout if you want to be a part of something?'

Hitting a nerve, the two continue to bicker as Cooper, 38, yells: ''Oh my God! All you f***ing care about is your God damn show man!'

And failing to control his temper, Bradley picks up a vase and throws a fern at Zach before hitting him over the head and walking off the set.
