The singer has recently been announced as the latest face of Avon and is keen to use her new role by helping fellow females become more confident.

She said: ‘I love to teach women that they should feel confident and feel good about themselves for themselves.’

Keri is replacing Jennifer Hudson as the cosmetic firm’s newest spokesperson and says it’s a dream come true.

She said: ‘I love fragrance. I love beauty.’

Avon is also pleased at the new partnership and think she is the perfect person to represent the brand.

Lily DeStefano, executive director of Avon North America Beauty, told WWD: ‘We had a great partnership with Jennifer Hudson, and we found that so powerful that, in the same spirit, we wanted to take it a step further. Keri just brings a youth and vitality to our brand. I think that she’s just the perfect transition.’

Keri, 27, will now join Reese Witherspoon, Zoe Saldana and Fergie as Avon faces.

The ‘Avatar‘ actress admits to being a bit of a tomboy and her clothing choices veers toward that side of her.

She told Self magazine: ‘I’ve never really been that feminine. Look in my closet and you’ll see things that are elegant, sexy, tomboyish, sophisticated, beautiful, aggressive.

‘It’s harsh. It’s a lot of black. Pretty is the last word you would think of.’

Zoe - who also starred in ‘Star Trek‘ – said her take on fashion stood out against the bright Caribbean fashions of her native Dominican Republic.

She said: ‘The Caribbean is the most floral-happy culture in the world, and my sisters and I were like three little Jackie O’s with big sunglasses, reading all these sophisticated magazines and dressed in black at all times.’

Zoe does, however, occasionally wear bright colours and on a recent shoot picked out a floral dress which brought back fond memories for her.

She explained: ‘These florals tell a story. I was channelling that South Beach-looking-for-a-millionaire-husband-from-Switzerland kind of thing. I live in constant storytelling mode.

‘Sometimes, I have to give myself permission to be pretty.’

The ‘Avatar’ actress says she has always been in to fashion and used to experiment with her look while she was growing up.

She said: ‘In high school I was a little bit of everything. Sometimes I would want to dress like a cheerleader or like a mean girl or the Sci-Fi geek that I usually was. It all depended on my mood, but I always knew that I loved fashion.’

Zoe, 31, says her love of clothes stems from her mother, who always encouraged her to take pride in her appearance.

She said: ‘My mum is from the Caribbean so her advice has always been incorporate colour in your wardrobe. I always end up dressing in black and white – the New York state of mind. But I really do try to listen to my mom’s advice.’

The ‘Star Trek’ beauty also revealed she is a huge fan of up-and-coming designer Prabal Gurung, after seeing his show at New York Fashion Week.

She told People magazine: ‘I just went to the Prabal Gurung show and I was absolutely smitten by all their clothes. I was absolutely thrown back by his beautiful collection. There was definitely this black dress that he had with a leather belt and I went crazy for it. I was like, ‘I must have that!’ ‘
