Bec was busy organizing New Year's celebrations this week, throwing a party for her glamorous friends at her sprawling $7.3 million mansion in Melbourne's posh Brighton.

She invited a who's who of guests to the exclusive bash, including radio star Lauren Phillips, celebrity stylist Lana Wilkinson and Yummy Mummy star Lorinska Merrington.

The mother of four posted to Instagram on Tuesday a group photo of some of her party guests posing together on the tennis court attached to her incredible home.

In her caption, Bec revealed that her party was a celebration of both the New Year and her 13th wedding anniversary with husband Chris.

Bec rang in the new year this weekend by throwing a party for her glamorous friends at her sprawling $7.3 million mansion in Melbourne's posh Brighton.

'Nice evening to celebrate New Year's Eve and our wedding anniversary. I got the standard photo with the ladies (a few are missing) while the husbands were inside,” she wrote.

The guests were dressed in futuristic clothing, while balloons in the shape of aliens could be seen in the background.

Co-founder of Bec's Jaggad activewear brand Michelle Greene, Lauren Phillips' aviation magnate Paul O'Brien, AFL WAG Kylie Brown and cricket WAG Rebecca Marsh were also spotted among the crowd.

However, there were a few notable faces missing from the audience: Bec's longtime friend and former WAG Nadia Bartel, and fashion designer Effie Katsaounis.

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

They have since welcomed four children: son Oscar, 12, daughter Billie, nine, and seven-year-old twins Tom and Darcy.
