DJ Waley Babu: Mahira and Sheheryar turn rappers

Looks like the two stars are having a lot of fun during Ho Mann Jahaan promotions

Mahira and Sheheryar -- who will soon be seen together in Ho Mann Jahaan -- seem to be having a lot of fun during promotions.

And what's the most fun activity these days? Making Dubsmash videos obviously! Mahira posted a video on Instagram of the two stars lip-syncing to popular song DJ Waley Babu.

Apart from the matching shirts, what caught our attention was Sherheryar's nickname. 'Munna the ladykillaaa!' han? Wonder what that's about!

Ho Mann Jahaan will hit theaters on January 1 and also features Adeel Husain and Sonya Jehan.

In a recent interview with The Express Tribune, Sheheryar said playing Arhaan -- his character in Ho Mann Jahaan -- was a real challenge. "It was a lot of work. Words like ‘interest’ were supposed to be pronounced as ‘intrast’. It took me a while to absorb the style and tone,” he said.

The young actor -- who is also producing the film -- said he is "married" to the film: “I have been married to the film for the past 14 months. We worked 14 hours a day for an entire year. We were all knit together. We celebrated every little achievement. First day of shoot, first song; had we not done that, we wouldn’t have been able to come up with the film.”
