WATCH: Kelly goes back to school

And the award for best (and fastest) mom goes to Kelly K!

It was her son, Christian's school sports day on Saturday and so Kelly naturally went along to offer her little man support.

Kelly was a real dotting mommy at the sports day, taking loads of snaps and  adorable video's of 6-year-old Christian.

And although Christian didn't win his race, to which Kelly joked " eish he definitely didn't take after me when I comes to running", he did win over our hearts.

Oh, and when the intercom called for moms to participate in the infamous parent's foot race, Kelly jumped at the chance, obviously!

See how she did:
