According to AOL Music:

Our favorite celebrity rebel, Pink, has posed topless for photographs taken by rock icon Bryan Adams. The “Here I Am” singer has become a well-known photographer and is working on a book of celebrity portraits entitled “Exposed,” for which Elton John penned the foreword.

Though the book features photographs of Mick Jagger, Amy Winehouse, Michael Jackson, Elton and many more celebrities, Adams said he’s particularly pleased with the snap he took of Pink.

Bryan told Billboard.com “It was a nice day and it was kind of hot outside. I suggested it might be a good idea; she said to me, ‘Not even my husband talks to me like that,’ and then off came her T-shirt.”

Pieces from the book were recently shown at the Museum of Multimedia Art in Moscow, Russia. The show will also be exhibited in Hamburg, Germany before arriving in Dallas, Texas in December.
