Irina Shayk thinks ''every woman'' is ''sexy''.

The 31-year-old model - who has nine-month-old daughter Lea with partner Bradley Cooper - insists it's what is on the inside that counts, rather than wearing a particular item of clothing or a certain style of make-up.

She said: ''For me, it's not about wearing high heels or red lips. Great underwear definitely helps, but feeling sexy definitely comes from inside.

''Any woman can feel sexy, and every woman is sexy in her own way.

''Just an expression or a smile can make a woman look super sexy.''

And the Sports Illustrated beauty thinks confidence also comes from within.

Asked what or who makes her feel confident, she told LOOK magazine: ''Myself. I don't believe somebody else has to make you feel confident. It should come from within.''

Irina is very ''proud'' of her family and they are always a huge source of inspiration for her.

She said: ''Both my grandma and my mum [have been influential]. I grew up in a family of women and I learned a lot of things about how to be strong and never give up, how to go my own way and make my dreams come true.

''And in my family, we always supported each other - I can proudly say I have the best family in the world. My grandma always inspired me.''

The Russian beauty couldn't be happier with her life right now.

She said: ''The most important thing is to be at peace inside and be happy.

''I enjoy every moment of my life and I'm really grateful for everything God has given me.''
