Mumbai, Jan 25 (IANS) John Abraham, who starts shooting for Karan Johar's untitled production in two months, has discovered a mutual giggling society with the ace director.

'When we're together, Karan and I both laugh and giggle to the point that people stand and stare at us. In fact, when we were in Delhi for the launch of the Nano car, Karan and I just cracked up repeatedly,' John told IANS.

Karan, who has teamed up with Simi Garewal for NDTV Imagine's 'Shava Shava', laughs at the mention of John.

'Not too many people know this, but John has a wicked sense of humour. We do have good laughs whenever we get together. Knowing our schedules, it isn't that often. But he's someone who can make me laugh,' said Karan.

Though he doesn't show it, the past year hasn't been easy for John.

'No Smoking', the film he saw as his career's turning point, bombed. And then there were rumours about turbulence in his relationship with Bipasha Basu.

Just when he was on the verge of starting afresh this year, his father again fell ill. But John's not sulking.

'All's okay and I'm pretty sure he's going to be all right. Nothing can be more painful than a parent's illness,' said John.

'When either of my parents is unwell, my life just comes to a standstill. I can't focus on anything. No wonder Karan Johar said, 'It is all about loving your parents' (in 'Kabhi Khushi Kabhie Gham'),' added the actor, who is now looking forward to Karan's film to be directed by Tarun Mansukhani.

'I am really looking forward to that. I've worked with Karan before in 'Kaal'. But this is something that has never been done before. And I'm with two of my favourite co-stars - Priyanka Chopra and Abhishek Bachchan.

'I just love all the Bachchans to death. The last time we were together for 'Dhoom', Abhishek and I just freaked out. I think Karan's film will be loads of fun.'
