Lily Allen doesn't ''believe'' in marriage.

The 34-year-old singer - who was previously wed to Sam Cooper, the father of her daughters Ethel, seven, and six-year-old Marnie - insists the institution is simply a ''contract'' for the government or the church and neither are important to her.

She said: ''Marriage is a contract between the government and/or god. Neither of which I believe in.''

The 'Trigger Bang' hitmaker admitted she tried to ''avoid being a woman'' growing up because of her relationship with her father, actor Keith Allen, and had to start ''liking'' other females when she had her daughters.

She told Stylist magazine: ''When I was growing up I had a very fragmented relationship with my dad.

''The way he spoke about women with his friends was quite derogatory so I tried to avoid being a woman.

''I didn't really bond with women and I felt jealous of women. Then, when I had my two girls I was like, 'OK, I guess you're going to have to start liking women now, Lily'. 'But it's been a complete blessing.''

The 'Smile' hitmaker loves social media, particularly Instagram, because it offers an ''insight'' into different areas of people's lives.

She said: ''The website I visit most often is Instagram [and] the best thing about social media is [having] insight into other people's life experiences.''

However, Lily has learned not to look herself up online.

She said: ''When I google myself I get sad.''

And Lily praised the internet for helping kick-off her award-winning music career, but admitted she would be a lot ''happier'' if there wasn't negative comments from trolls online.

She simply said: ''Without technology I would probably be happier but less successful.''

The full interview appears in this week's issue of Lily Allen takes over Stylist, which is out now.
