Los Angeles: Celebrity photographer Terry Richardson has been accused by a British model for demanding sex while offering a photo shoot in a magazine.

Model Emma Appleton tweeted a screen grab of a message allegedly sent from Richardson's Facebook account, which offered a Vogue photo shoot in exchange for sex. The photographer, who has also worked with Miley Cyrus, Lady Gaga and Taylor Swift as a music director, has denied the allegations.

Candice Marks, a spokesperson for Richardson, told Buzzfeed, "This is obviously a fake. Terry did not send this text." Appleton, however, told Buzzfeed that it came from Richardson's Facebook account. But she later deleted her tweet.

"Beginning to wish I hadn't posted that... it doesn't matter who you are or what the industry is, just be a decent human being," she tweeted before deleting her account. When the Wrap contacted the Vogue magazine, they said they have no plans to work with Richardson.

"The last assignment Terry Richardson had for US Vogue appeared in the July 2010 issue and we have no plans to work with him in the future," Hildy Kuryk, communications director for US Vogue said.
