Photographs of Bruce Jenner wearing a dress outside his Malibu home have sent Twitter into a frenzy, as celebrities and fans have spoken out in support of the reality TV star.

Jenner, 65, was reportedly photographed by paparazzi, wearing a striped max dress, while smoking a cigarette.

The photographs, which were published in the New York Daily News, have provoked outrage at the intrusion into the star's privacy.

Several celebrities have spoken out in support of Jenner decrying the lack of respect for the former Olympian, who is to go public about his plans for gender reassignment in a forthcoming interview with ABC's Diana Sawyer.

Big Brother host Rylan Clarke tweeted his support for the TV star writing: "Genuine good luck to Bruce Jenner... I hope she will be happy, looking good in a maxi as well! #GoBruce x"

Girls actress Lena Dunham defended the Keeping Up With The Kardashians star writing: "Dear Stranger: if you're making unkind Bruce Jenner jokes you have me to answer to. I seriously feel protective this week"

Celebrity blogger Perez Hilton described Jenner as "a genius" while controversial shock jock Howard Stern was more concerned with the choice of dress than the fact that Jenner was wearing one. "Bruce, you're a large lady. Don't wear stripes, especially horizontal stripes."

Fans of the star were also vocal in condemning the negative reactions on social media to the pictures.

"If you've got a problem with seeing Bruce Jenner in a dress you've got a serious problem in general. Live and let live. Best of luck to him," tweeted Harry Cook.

"It's so brave of Bruce Jenner transitioning this late in his life knowing the scrutiny he'll be under, I hope he's finally happy," tweeted another supporter.

Chloe added: "I feel so bad for bruce jenner he obviously wants to keep his transition private and people just won't leave him alone :/."

"I admire Bruce Jenner so much for what he/she is doing. Absolutely incredible," wrote another.

Earlier, 80s pop star Boy George said Jenner has his "150 per cent support in every way" and applauded the reality star's brave decision to speak about transitioning.

In an interview with People magazine the singer said: "I absolutely applaud what he's doing and I think it's very brave. And it actually makes me quite emotional. He has my 150 per cent support in every way. I think that the whole transgender thing is the new frontier," he added.

In stark contrast, Jenner was the subject of mocking emails sent by director Cameron Crowe to former Sony Pictures studio head Amy Pascal. The offensive comments emerged after thousands of leaked emails were published on Wiki leaks.

It has been reported that Jenner now plans to take legal action against the photographers for taking the photos on private property without consent.

A source told "Bruce has decided to take legal action because he is fed up with the constant invasion of his privacy,".

"Bruce chose the secluded hilltop home for a reason, to get away from the paparazzi that have hounded him for years — he was forced to call the cops on Tuesday because paps were using zoom lenses to get pictures of him in the house," the source added.

In the eagerly anticipated two hour interview, the former athlete is expected to open up about his transition. In a promo for the interview he says: "My whole life has been getting me ready for this."

Jenner is also expected to reveal how ex-wife Kris Jenner, daughters Kendall and Kylie Jenner, and step-daughters Kourtney, Khloe and Kim Kardashian, have reacted to the gender reassignment news.

The two-hour special Bruce Jenner: The Interview, is scheduled to air on ABC on 24 April.
