Beyonce covers US Vogue September issue, opens up on her relationship with Jay Z, birth of her twins (Photos)

Beyonce is the cover star of US Vogue Magazine's iconic September issue, and music superstar strikes a fierce pose under the cover line 'Everyone's voice counts, Beyonce in her own words.' 

In the issue, Beyonce wrote a personal essay for Vogue where she opens up about her two pregnancies, her relationship with husband Jay Z, learning to love her body and exploring her ancestry. 

The 36-year-old mother of three also revealed she underwent an emergency Caesarean section when she welcomed her twins in June 2017.

'I was 218 pounds the day I gave birth to Rumi and Sir. I was swollen from toxemia and had been on bed rest for over a month. My health and my babies’ health were in danger, so I had an emergency C-section' she wrote.

Beyonce is also mother to Blue Ivy, six, with hip hop heavyweight Jay-Z, 48, and revealed she felt pressure to snap back into shape within three months after her daughter was born which, looking back, she now feels was 'crazy'.

After her twins, the songstress went about things very differently.

'I gave myself self-love and self-care, and I embraced being curvier. I accepted what my body wanted to be. After six months, I started preparing for Coachella. I became vegan temporarily, gave up coffee, alcohol, and all fruit drinks. But I was patient with myself and enjoyed my fuller curves. My kids and husband did, too.' she revealed.

Beyonce 'stripped away the makeup, wigs and hair extensions' for her Vogue shoot and wrote that 'it's important for women and men to see and appreciate the beauty in their natural bodies'.

'To this day my arms, shoulders, breasts, and thighs are fuller. I have a little mommy pouch, and I'm in no rush to get rid of it. I think it’s real.' she confessed. 

For now Beyonce says she's happy with herself but knows what she needs to do when the time comes to transform her body. 

'Whenever I'm ready to get a six-pack, I will go into beast zone and work my ass off until I have it. But right now, my little FUPA (fat upper pubic area) and I feel like we are meant to be.'

The mother-of-three also touches on her relationship to the rapper - who she celebrated 10 years of marriage with this year - writing that she's been to 'hell and back'.

Jay, born Shawn Corey Carter, publicly admitted he had been unfaithful to Beyonce in an interview with the New York Times' magazine last year, years after cheating rumors circulated.

Beyonce wrote, 'There are many shades on every journey. Nothing is black or white. I’ve been through hell and back, and I’m grateful for every scar. I have experienced betrayals and heartbreaks in many forms. 

'I have had disappointments in business partnerships as well as personal ones, and they all left me feeling neglected, lost, and vulnerable. Through it all I have learned to laugh and cry and grow.'

Growing up the singer has learned that she no longer needs to try to make everyone happy.

'I look at the woman I was in my 20s and I see a young lady growing into confidence but intent on pleasing everyone around her. I now feel so much more beautiful, so much sexier, so much more interesting. And so much more powerful.' 

The singer also delved into her ancestry recently and she revealed that she found out she's descended from a slave owner who married a slave. The discovery has shaped the way she wants to raise her children.

'I come from a lineage of broken male-female relationships, abuse of power, and mistrust. Only when I saw that clearly was I able to resolve those conflicts in my own relationship.

'I researched my ancestry recently and learned that I come from a slave owner who fell in love with and married a slave.' she wrote.

'I had to process that revelation over time. I questioned what it meant and tried to put it into perspective. I now believe it’s why God blessed me with my twins. Male and female energy was able to coexist and grow in my blood for the first time.

'I pray that I am able to break the generational curses in my family and that my children will have less complicated lives.'
