Sunny Deol goes from serious to playful!

The once reticent Sunny Deol seems to have suddenly shed his inhibitions on sets of 'Yamla Pagla Deewana 2'

Sunny Deol is a changed man. The actor, well known in B-Town for maintaining a low profile and being reticent, has suddenly shed his inhibitions.

The dhai kilo ka haath hitting star is letting himself go and how! He's turned party-hearty and displaying his fun streak to all. The brawn icon has been in England for the past two months shooting with father Dharmendra and brother Bobby for the sequel of their 2011 comic caper.

The buzz from the sets of the Sangeeth Sivan directed film is that he is keen to change his serious tag image. For someone who detested being the centre of attraction, it has come as a surprise to see the Punjab da puttar wanting to be the cynosure of attention! Says a unit source, It is clear that Sunny has become extremely forthcoming. For a man who always shunned media glare, he is now loving the attention and does not mind the publicity blitzkrieg. He is no longer holding back and seems to have decided to go the way the other stars go be in the media glare.

One look at Sunny's recent snapshots amply denote his metamorphosis. On November 1 at his co-star Russia-born model Kristina Akheeva's birthday bash, Sunny was in the thick of things including lifting the birthday belle. He even insisted on plastering the newbie's face with cake.

On his birthday (October 19), Sunny had a blast celebrating his big day as well as when it was director Sivan's birthday in September. As the source says, Sunny has been in the industry for decades, when has anyone seen this side of him in public glare? For a man who guarded his privacy, this is definitely a surprise.

So who is responsible for the changed Sunny? Is it his son Karan (better known as Rocky) who is the AD for the film? Or blame it on the English weather? Whatever (or whoever else) is the reason it's good to see the shy Sunny come out of his shell.
