New York, Sept 4 : World No. 2 Rafael Nadal, who has become the new face of both Armani Jeans and Emporio Armani Underwear, revealed that posing in an undergarment is very `tricky'.

A 20-foot banner of his famous mug, naked torso and a hint of denim was unveiled recently at Macy's.

And according to him, though posing in underwear is nothing `really new', he has always been shy while dealing with it.

"Well, that's nothing really, really new. But for sure it's always . . . I'm a bit shy, which you saw [in the unveiling]. With underwear, it's always tricky," the New York Post quoted him as saying.

He also revealed that he has never been scared to shoot for Armani for their amicability.

"With the shootings? No. The people from Armani are always very nice with me," he added. (ANI)
