Lady Gaga shares naked photo

Lady Gaga has shared a picture of herself naked on the toilet.

The 'Born this Way' hitmaker is seen holding a cigarette and pouting in the photograph, which was taken by acclaimed photographer Terry Richardson - who she previously worked with on the book 'Gaga x Terry Richardson' - and posted on her website littlemonsters.com.

It was accompanied by the cryptic caption ''Lady Gaga Unretouched #2''.

Meanwhile, the singer has also spoken out in support of gay marriage, to back France's plans to officially introduce same-sex unions.

She said: ''It seems to me that gay marriage is something that is going to happen and it must happen.

''We are not equal and we will be only if we allow everyone to love freely.''

Following Pope Benedict XVI's apparent criticism, labelling same-sex relations as defective and harmful to society, she also argued against what she sees as his non-Christian stance.

She added: ''This is not what Christians believe. It is the point of view of one person.''
