Pop star Lady Gaga has posed topless wrapping a clear plastic sheet around her for a poster to promote her Born This Way Ball world tour.

The only cover up underneath the transparent wrap is a pair of lace-up platform boots, and she has not let go of a hat, reported Sun online.

The 25-year-old unveiled the artwork for the forthcoming tour earlier this week, showing a ghostly, gothic face over a medieval castle.

She said that the first batch of dates for the shows will kick off in Soeul, South Korea, April 27 and run into 2013.

"The Born This Way Ball will perform 110 shows around the world," Gaga tweeted.
The 'Poker Face' singer also said that she feels worn out after working on arranging props for the show.

"Been working like crazy all day. Need to smoke a joint or something, or maybe just a good punch in the face. props props props," she had tweeted.

Gaga's last tour, Monster Ball, stretched from 2009 to 2011, and was a huge hit.

She played to 2.5 million fans over 200 dates and grossed a massive 143 million pounds.
