Several of the accuser have spoken about their encounters with the photographers in details in The New York Times article, which can be read in full here.
Of the 15 male models who have accused Weber, one in particular, Robyn Sinclair, told The New York Times, "I remember him putting his fingers in my mouth, and him grabbing my privates".
Weber's racy advertisements for Calvin Klein, Abercrombie & Fitch and other companies helped turn him into a star in commercial and fine art photography.
Testino, who took the Duke and Duchess of Cambridge's official engagement photos and was given an honorary OBE in 2014, was accused by 13 male assistants and models of subjecting them to sexual advances. Locke also alleges that Testino was "aggressive and flirtatious" throughout the shooting of a Gucci ad campaign, and that the photographer made unwanted advances towards him on the last day of the shoot. Representatives for both photographers are yet to respond to similar requests.
Mr Weber told the paper in a statement from his lawyer: "I'm completely shocked and saddened by the outrageous claims being made against me, which I absolutely deny". Meanwhile, the law firm that represents Testino has claimed that former employees were "shocked by the allegations" and "could not confirm any of the claims".
Actor Kevin Spacey was booted from various major projects after he was accused of sexual misconduct by multiple men. We never had sex or anything, but a lot of things happened. "A lot of molestation", he said of the American photographer.
"I'm the girl, you're the boy", the photographer allegedly told the model, who said he walked out of the room.
Hugo Tillman, a photographic assistant, said Testino pinned him down on a bed before being removed by another person. "[But] if you said you were not going to work with someone like Bruce Weber or Mario Testino, you might as well just pack it in and go work in another industry".
Recently, photographer Terry Richardson continued to work after being accused in a documentary of sexual assault of female models and denying their claims - until the Weinstein scandal broke.
Anna Wintour, artistic director of Conde Nast, which publishes magazines including Vogue and GQ, said the publisher would not work with the pair for the "foreseeable future" following Saturday's report.
"Today, allegations have been made against Bruce Weber and Mario Testino, stories that have been hard to hear and heartbreaking to confront".
"I believe strongly in the value of remorse and forgiveness, but I take the allegations very seriously, and we at Conde Nast have chose to put our working relationship with both photographers on hold for the foreseeable future", she said in a statement.
