The Twilight star, who once saw a ghost in her bedroom, was on the show to promote her latest project, Living for the Dead.

‘It was a bit of a peck, but I was 13 or 14,’ she added.

Her co-star in the on-screen love scene was Jamie Bell, 37.

Andy pointed out that the Billy Elliot star was ‘so sweet and so cute.’

Kristen agreed, but said, ‘I was so nervous, I was freaking out.’

‘And then the director, he could tell I was just red and f***ing non-responsive. And he was like, “It’s just little butterfly kisses,”‘ and I was like, “That didn’t help! Whatever that means, I don’t understand it!”‘

The star who was styled in a black and white houndstooth plaid jacket over a black top and shorts with ankle boots, joked that she was ‘in therapy’ after the teenaged buss, but that she and her former co-star, who is happily married to Kate Mara, were still friends.

‘Yes, I love Jamie,’ she said.

The actress, who is happily engaged to actress and writer Dylan Meyer, shed a bit of light on her own pending nuptials, indicating that she’s reached out to see if Food Network star Guy Fieri could officiate.
