Beyoncé included a copy of her birth certificate in her Cowboy Carter Tour Book, and one detail has stunned her fans. 

The Grammy winner, who launched her new haircare line last week, was born on September 4, 1981 in Houston, Texas at 9:47 pm, making her a Virgo with Aries as her rising sign.

A rising sign in considered important in astrology because it reveals your perception of reality, astrologer Aliza Kelly wrote for The Cut. 

It 'represents the microcosm of your entire life experience, including the themes, cycles, and patterns that will show up in your life over and over again,' she explained.

Aries rising means the hitmaker sees 'the world as a competitive, exciting, and spirited place,' according to Kelly who added, 'Winning isn’t just an aspiration; it’s a necessity for Aries risings, who believe that their destiny demands a victorious path.

Fans have been sharing screen grabs of the birth certificate on social media, and reacting to the new information. 

'Oh the astrology girls are going to have a field day with this. They thought she was a Libra Rising this whole time,' wrote one fan. 

'Oh my Aries sister. Explains the eyebrows,' stated another. 

'Just found out it's been revealed Beyoncé is an Aries rising. Sun in the 6th house, Moon in the 8th, and a 7th house Libra stellium plus Leo Mars in the 5th. Why is it all coming together?' wondered an avid astrology afficionado. 

'Her Aqua south node - she’s always filled with surprises. Can’t believe she’s an Aries rising,' maintained a follower.  

'People want Beyonce to be everything but a Virgo . Relax, perritas, it's a heliocentric world out there,' explained a follower.   

'She’s really a Leo Sun (in her 5th house) because that’s the actual planetary placements based on the sidereal calculations,' argued another, explaining. 

'This is why she wears gold, has constantly worn blond hair, is very attached to Oshun, is called Queen B, is featured in the Lion King movie, I could go on about how many references there are around her been the Queen. Leo is her soul essence.' 

Another interesting detail reveals that her mother's last name was listed as Beyince, and it appears her parents altered the spelling so her first name would be pronounced correctly. 

'So its originally “Beyince”?????' asked a fan. 

The stars seem to be aligned for Queen Bey to take her show on the road.

The Ameriican Requiem singer will kick off the Cowboy Carter tour April 28, with five shows scheduled for Los Angeles. 

International dates are scheduled for London and Paris, along with shows in her hometown of Houston, before completing the tour in Las Vegas July 26.
