Victoria Beckham gets girls moving after being visibly moved to Brand's tenth birthday

If you have a good time, slap it to the left!

Victoria Beckham was in the mood to celebrate this weekend, her fashion brand having celebrated her 10th birthday with a show at London Fashion Week.

The often stoic creator was clearly overwhelmed with emotion as she smiled, waved her hands in front of her mouth and applauded as her show went wild.

Beckham, 44, was wearing a camel coat and black pants on the catwalk, leaving her hair out of her ponytail with emotion.

She then posed with her parents on Instagram, writing, "What an amazing day, so grateful for all the support of my family x vb # vbsince08."

Beckham also posted a photo with her four children – Brooklyn, 19, Romeo, 16, Cruz, 13, and Harper, 7 – on Instagram. "Kisses," she captioned the family photo.

The best moment came during the Beckham after-party celebration, where she participated in the Spice Girls' song "Spice Up Your Life".
