Five celebrities on body image and sexuality in media
Female appearance, behaviour and sexuality in the entertainment industry have hit the headlines again this week.
Miley Cyrus had a go at "double standards" for men and women, after being criticised over her music videos and on-stage appearance.
Lily Allen has revealed that her latest single mocks the trend for naked women in music videos.
Celebrities including Jennifer Lawrence and Ariana Grande have also spoken out about their treatment by the media.
The star of The Hunger Games franchise has said hearing criticism from the media about her appearance "was like being in high school".
Speaking to Yahoo! employees about the US programme Fashion Police, the actress said shows like that make young people think "it's OK to point at people and call them ugly or fat".
Fashion Police host Joan Rivers replied on Twitter, saying the star loved the show when they were complimenting Lawrence on her style during Oscar season.
"It just dawned on me why Jennifer Lawrence fell on her way up to the stage to get her Oscar. She tripped over her own arrogance," added Rivers.
The singer, returning to the music industry after starting a family, said her new single Hard Out Here addresses how "difficult" it is for girls growing up.
"It [the song] is to do with a lot of stuff that's being talked about in the press actually, the sexualisation of children and the objectification of women in general."
Critics have said that the video, which uses black dancers, is racist and continues the stereotypes of black women in rap music.
Allen has responded, saying it is "a light-hearted satirical video that deals with objectification of women within modern pop culture".
Earlier this week Miley Cyrus said her on-stage persona and revealing outfits were all part of her act.
"I don't actually walk around all day twerking with my tongue out dressed as a teddy bear," she said.
The 20-year-old says she doesn't worry if people think badly of her controversial performances because she knows she is a "good person".
She added: "I feel like I'm one of the biggest feminists in the world because I tell women to not be scared of anything."
Ariana Grande is the latest artist to be launched in the UK by Scooter Braun, who is best known for managing Justin Bieber.
The 20-year-old rose to fame starring in Victorious on Nickelodeon and now features in the spin-off Sam & Cat. She has recently released her first album Yours Truly.
"There's no pressure to do anything," she said. "I dress the way I dress."
Speaking about the way Miley Cyrus has been represented in the media, she added: "They're criticising her so unfairly. She's just being Miley.
"Just let her do what she wants. If it's not for you, don't look. Shut up."
Speaking to the BBC about other female musicians, Lady Gaga said: "In pop music, in that particular sphere, there's a one-dimensional quality to sexuality so I think the difference between what I do and that, is there's an intention behind the sexuality.
"Most of the time I don't find myself to be sexy actually."
In September the musician responded to claims in the US media that she had gained weight by saying, "I am proud at any size."
She added: "I am not going to go on a psycho-spree because of scrutiny. This is who I am."
