Kym Johnson celebrates milestone birthday with heartfelt gift from her twins

Kym Johnson received a memorable surprise for her 50th birthday, thanks to husband Robert Herjavec and their 8-year-old twins, Hudson and Haven.

The former Dancing with the Stars professional shared videos on Instagram from her birthday celebration, showing the twins taking the stage to serenade their mother with a special song in front of family and friends.

In the clips, Haven wore a white layered dress while Hudson matched the occasion in black slacks and a white jacket.

Proud father Robert Herjavec watched from the side of the stage as the siblings delivered the heartfelt performance.

"The best gift of all," Johnson wrote alongside the post, thanking her husband and songwriter Darren Mapes for organizing the surprise.

She jokingly added that Herjavec "probably had to bribe them with a trip to Target," before saying the touching moment was one she would treasure forever.

The celebration comes after Herjavec previously reflected on how much Hudson and Haven have changed his life.

Speaking last year, the Shark Tank investor revealed that he and Johnson spent years trying to have children and once believed becoming parents together might never happen.

He described the twins as an incredible blessing, explaining that his daughter Haven's name was inspired by the feeling of gratitude the couple experienced after welcoming their children.

Herjavec also shared that his younger children are only beginning to understand what their parents do professionally.

While they recognise Johnson from her dancing career, they have gradually started connecting him with Shark Tank.

The entrepreneur recalled a humorous classroom moment when Hudson was asked to explain his parents' jobs.

Instead of giving a speech, he played footage of his parents' first dance from Dancing with the Stars, leaving classmates wondering why his father appeared alongside the professional dancer.
