London - Beyonce feels sexier since having a baby.

The 'Diva' singer - who gave birth to her baby daughter Blue Ivy Carter with her rapper husband of four years Jay-Z in January 2012 - has revealed that becoming a mother has improved her sex life.

The 31-year-old singer told the February issue of GQ magazine: "Giving birth made me realise the power of being a woman. I have so much more substance in my life. And expressing that excitement and that sensuality and the connection I have with my husband - I'm a lot more comfortable with that now. I actually feel like my child introduced me to myself."

The singer admitted she was angry when people thought she faked her pregnancy, saying: "It's not personal to me, and it comes along with the job, but the lack of respect - people will just go too far sometimes."

The 'Crazy In Love' hitmaker also opened up about her chemistry with Jay-Z and said it helps that they are both very independent.

She said: "I was independent before I met my husband, and we have such a natural chemistry and a genuine relationship, and it's based on the things that relationships are supposed to be based on. I've seen, growing up, when a woman or a man in a relationship - it doesn't matter which one - doesn't feel confident, they feel a bit trapped. Your self-worth is determined by you. You don't have to depend on someone telling you who you are." - Bang Showbiz
