Rebecca Judd is every inch the proud mother as she cheers her daughter Billie during race

She shares four children with her AFL star husband Chris Judd.

And Rebecca Judd was every inch the proud mother on Sunday as she watched her daughter Billie win a 400 metre race.

The WAG, 40, shared a video to her Instagram story of her nine-year-old daughter crossing the finish line.

In the footage, Billie can be seen running ahead of her competitors before finishing the race. 

‘I wish I’d filmed the whole race. Came from behind in a blinder and the finish is all I captured. Muted to save your ears,’ she captioned the post.

Rebecca and her husband Chris live in a $7.3million mansion in Brighton with their four children.

The home boasts a gym, a tennis court that can be turned into ‘a footy oval or cricket pitch’, and a magnesium salt pool.

There is also a spacious wet bar complete with a snooker table and a bar.

The couple celebrated her 12-year wedding anniversary last month, with Rebecca sharing a touching tribute to her husband and family.

She shared memories of her wedding day to AFL great Chris on her stories.

’12 years married today. 19 years together. 4 amazing kids. Time to get a dog,’ she captioned the post.

The Judds met at a pub in Perth 17 years ago when they were both teenagers, and wed on December 31, 2010, at Melbourne’s Albert Park.

They tied the knot in a spectacular ceremony on New Year’s Eve.

They have since welcomed four children: son Oscar, 11, daughter Billie and sixth-year-old twins Tom and Darcy.
