'Happy Bhag Jayegi',the forthcoming film of Abhya Deol and Diana Penty creating a buzz as a few days ago, the team attended the music launch of the film.Everything was going normal until Mika Singh cracked a rather crass joke on actress Diana Penty's surname. Mika first called her Dina and when corrected,made the remark,"Diana Panty and Mika Kachcha." Diana Penty used to keep silence at time but kept her cool on stage but this silly comment from the singer's side did not sit well with the actress.. But after the actress made a simple and honest statement about the incident which just goes to show that nobody really likes Mika's jokes. Diana said,"I don't find these jokes funny. I don't even understand how people laugh at such comments."
