Beyonce melts hearts as she dances with son Sir, 3, in rare video

Beyonce has fans in a spin after she was captured on video dancing with her son, Sir.

Doting mum Bey swung the three-year-old from side-to-side, Sir looking extremely dapper in a miniature Giorgio Armani suit and a rainbow unicorn headband.

Filmed by Bey's pal and stylist Manuel A Mendez, the songstress couldn't help but beam as the tot clung onto her neck.

Sir has a twin sister, Rumi, as well as older sister Blue Ivy, eight.

Beyonce shares her three kids with rapper, entrepreneur and hubby Jay-Z.

Manuel has worked with the Carter family for years, and has been styling Blue since she was a baby for public appearances with her mega-star parents.

Beyonce's been kept busy in recent months following the August release of her latest studio album, Black Is King.

As a visual album, it features appearances from her family, including Jay, their kids, and mum Tina.

Celeb pals Pharrell, Jessie Reyez and Naomi Campbell also show their faces, as does Bey's former Destiny's Child bandmate Kelly Rowland.

Beyonce opened up about what motherhood means to her last year, sharing: "Being a mother, my family is my biggest priority.

"It's not many films that the parents can come and feel the way I feel about The Lion King and feel that and pass that legacy onto their kids."

And Beyonce and Jay recently celebrated 12 years of married life, having tied the knot in a famously low-key ceremony in Jay's New York City apartment in 2008.

They welcomed Blue in 2012, and twins Rumi and Sir in 2017.

Tina led tributes to the pair on their 12th anniversary, sharing a previously unseen wedding day snap.

Beyonce throws an arm into the air while rocking a classic, crisp white wedding dress, Jay looking dapper in his tux.

"It seemed like yesterday these guys walked down the aisle," proud mum Tina wrote, "Such beautiful memories of that day, now it's twelve years later.
