Mumbai, Aug 14 (IANS): The second poster of Aamir Khan's "PK" will come out Aug 20 and he says in that, he's not even holding a boombox, which hid his modesty in the first poster that received flak for the actor's naked look.

In the first look poster of the film, Aamir posed nude with a strategically placed boombox. While some appreciated the dare bare act, some criticised it and even called it a "publicity stunt".

"We are releasing our second poster for 'PK' Aug 20 and in that poster I am not holding any transistor even," Aamir told reporters here Wednesday at the launch of a book "My Marathi".

In "PK", Aamir will be seen speaking Bhojpuri. The actor says he took special training under a dialogue coach for two years.

"I took special training for Bhojpuri language as I am speaking Bhojpuri in 'PK'," the 49-year-old said.

"I took special training for it for almost two years from my dialogue coach Shanti Bhushan," he added.

Directed by Rajkumar Hirani, "PK" also features Sanjay Dutt, Anushka Sharma and Sushant Singh Rajput. It is slated to release Dec 19.
