We all have that one buddy who makes us laugh out loud, gives us their shoulder to cry on and with whom we've shared a lot of memorable moments.

This sentiment is reflected in Mera Yaar Funtastic, the new single of director Ashish R Mohan's Welcome 2 Karachi for producer Vashu Bhagnani. As the buzz about the number increases, we quiz the team of the film about their most 'funtastic' friend.

Vashu Bhagnani:Not only do we have the best working relationship but David Dhawan is also my craziest, funniest yaar. He's got a great sense of humour and our daily calls to each other are peppered with inside jokes and filmi anecdotes. One conversation with him is enough to have me smiling all day.

Arshad Warsi:I've grown up with my best friend. There is nobody in the world who understands me like he does. His name is Arshad Warsi. I am my own best friend!

Jackky Bhagnani:Gautam Gupta is my best friend. I've known him for more than

15 years and some of my most fabulous memories have been with him. All my girlfriends have always been insecure of him and if he were a girl, I'd marry him!

Lauren Gottlieb: My most funtastic friend is Gerry Conedi. He has been my best friend for the last decade and was sporting enough to accompany me to India when I came here to shoot my first film. We had the most amazing time together in India - from trying local street food to travelling all over the country's beautiful locales, I experienced all my first desi moments with him!
