The pair spent Beyoncé's special day by hanging out at the Made in America festival in Philadelphia, which was set up by her husband Jay Z.

The festival featured performances from acts such as Coldplay and DJ Khaled, and the 'Motivation' singer said she was "super excited" to watch them all perform.

"We are all going to be celebrating this festival and Beyoncé's birthday! We are all going to be together. I am getting ready to see her now!"

Celebrities from all around the world took to social media to celebrate the birthday of the 'Lemonade' hitmaker.

Kim Kardashian West, Mariah Carey, and Nicki Minaj were among those to wish her all the best.

Coldplay frontman Chris Martin - who worked with the beauty on 'Hymn For The Weekend' - said during his performance at the festival: "We want to say happy birthday to Mrs. Carter who is out here somewhere.

Can you believe she is 107 years old? Happy birthday Bey."

The next phase of birthday celebrations comes after the 'Run The World' musician - who has four-year-old daughter Blue with her 45-year-old rapper husband - marked the special day by sharing the music video for her song 'Hold Up' with her fans.
