Mario Testino has teased the contents of his book 'Sir' on social media.
The 62-year-old fashion photographer has announced his text, which was originally published last year and features portraits of iconic male figures he has worked with over the past thirty years, is available to buy in ''soft cover'' now.
And the highly recognised figure has given a sneak peek of what's inside on his Instagram account, and has unveiled images of 'Rolling Stones' band members Keith Richards and Sir Mick Jagger, as well as Orlando Bloom planting a kiss on David Beckham's cheek.
Mario - who is known for his Towel Series photoshoots with celebrities - shared a picture of the cover of his book, which features a male grabbing at their crotch, on the picture-sharing website.
He captioned the post: ''MY BOOK 'SIR' IS OUT TODAY IN SOFT COVER!
MY LIBRO 'SIR' SALE HOY EN TAPA BLANDA!
See link in bio. @Taschen #MarioTestino #TestinoArchive #Taschen (sic).''
And the star followed this post by uploading a black and white image of fashion designer Karl Lagerfeld, which is included in 'Sir'.
He captioned the post revealing the contents: ''THE ONE AND ONLY MR. LAGERFELD FEATURES IN MY BOOK 'SIR', OUT TODAY IN SOFT COVER!
EL ÚNICO SR LAGERFELD DESTACADO EN MI LIBRO 'SIR' QUE SALE HOY EN TAPA BLANDA!

Mario also added a link to purchase his book, which features 300 pictures, and revealed it is being retailed for £49.99 in a temporary slideshow on Instagram that lasts for 24 hours.
Meanwhile, Mario - who has worked with catwalk icons including Naomi Campbell and Karlie Kloss - has been credited as 21-year-old model Gigi Hadid's ''friend''.
Speaking previously about the fashion mogul, she said: ''@mariotestino - it will forever be an honour to be in front of your lens & to learn from you; most of all, I'm so grateful to call you my friend. Thank you for the adventures and the laughs (sic).''
