Beyonce's mum Tina Knowles Lawson has paid tribute to her superstar daughter with a sweet post on Instagram on the star's 37th birthday.

Fashion designer Tina shared an adorable throwback photo of Beyonce from when she was just four months old.

The 64-year-old mother of two, she also shares daughter Solange, 32, with Beyonce's father Mathew Knowles, praised the Lemonade hitmaker for her hard work and for being both generous and loving.

“Happy Birthday to the nicest, owner of the most beautiful, generous, loving hearts ever !!!! Brilliant too! Always thinking, planning, analyzing, strategizing, how you can make everything you touch better!” she wrote on Instagram on Monday (03Sep18), hours before Beyonce’s birthday on Tuesday.

“Sometimes I can’t believe out of all the incredible people in the world I was chosen by God to be your mom!” continued the proud parent, who is also a grandmother of four.

“The day that you and your sister entered this world were the two best days of my life, hands down!! It is a privilege to have carried you two in this body. … No one deserves it more!” Tina ended the post, adding red heart emojis and bee emojis.

Beyonce recently performed in Miami with husband JAY-Z for their On the Run II Tour, which is now on a break and scheduled to resume on 11 September at AT&T Stadium in Arlington, Texas, leaving plenty of time for birthday celebrations.

Last year Jay used part of his set during his appearance at the Made in America music festival to lead the crowd in singing a birthday song to his wife, who watched from the side of the stage, and was caught in video on social media smiling from the audience, and dancing along.

She was also surprised with a special tribute video featuring famous friends, including Michelle Obama and Serena Williams, who got in formation by recreating Beyonce’s iconic look from her Formation music video.

Former Destiny’s Child bandmates Michelle Williams and Kelly Rowland also participated in the tribute, alongside Tina, and Jay’s mother Gloria Carter, and his grandmother, Hattie White.
