David and Victoria Beckham's youngest child, five-year-old daughter Harper, had a fangirl moment on 14 October, when her doting father took her to a Justin Bieber concert in London's O2 Arena. As the youngest member of the Beckham family swayed to the rhythm of her singing idol's hit track Life Is Worth Living, the former footballer captured the moment in an adorable video.

Sharing the sweet clip as an Instagram story, the father-of-four scribbled "JB" in a purple shade to explain who his little angel was cheering on.

In the video, Harper is seen waving a mobile phone in the air as she swings to Bieber's music in her family's private box. Dressed in a white frilly dress, Harper made for quite a sight.

After the concert was over, David seemed to be a busy father as he chauffeured his children — Brooklyn, 17, Romeo, 13, and Cruz, 11 — and Harper back home. Huddled in their family's SUV, the Beckhams even sported similar caps as they left the spot.

This is, however, not the first time that the English soccer player has come out as a loving father and family man. Previously, his wife and fashion mogul Victoria had gushed about her better half during an interview with Vogue Australia as she revealed the supportive side of her husband.

"It is difficult to maintain it all in terms of being a wife, mother and businesswoman leading a brand. But I have a great team and I have a husband who is incredibly supportive," she had said in the November edition of the magazine.

"David and I are very, very present as parents and I think that's the most important thing. We both work but we have great relationships with our children," she added.
