One is the former wife of Cricket legend Michael Clarke, while the other is the wife of Tennis champion Lleyton Hewitt.

And it appears Kyly Clarke and Bec Hewitt have plenty in common, as the House Rules presenter has revealed the pair are childhood friends.

Posting to her Instagram on Saturday, Kyly, 39, she 'misses' her actress pal, 37, and looks forward to reuniting with her 'sister' on Dancing With The Stars.

Sharing a photograph in which she posed alongside Bec, Kyly wrote: 'Miss you so much already @becHewitt.'

'Known this beautiful girl since she was around eight years old... absolutely adore our friendship, you're like a sister to me, can't wait to have you back on Sydney ground otherwise I'm coming for you Melbourne.

'Getting to share the dance floor with you again was an unbelievable feeling,' she added.

The women have been friends for a solid 31 years. In 2015, the duo posed together at a barbecue as they celebrated 23 years of continued friendship.

Former weather girl Kyly took to Instagram to express her joy at catching up with the Bec, writing: 'Soooo good to see my dear friend! What a great 23yr friendship! Good times and a great catch up #cricket #bbq #family.'

Despite their close friendship, the pair are about to become rivals as they compete for the crown on the new season of Dancing With The Stars.

Kyly debuted on Dancing With The Stars back in 2014 and will return for the All Stars special with her hunky Italian dance partner Gustavo Viglio.

Meanwhile, Bec who won the very first season of DWTS in 2004, is partnered with dancer, Craig Monley
