AFL WAG Bec Judd will celebrate her 40th birthday on January 27.

And rumours have surfaced that the notorious party girl and mother-of-four has big plans in store to celebrate one of life's milestones.

According to the Herald Sun on Friday, Bec has booked out the Mitchelton Winery for the festivities.

Situated 137km from Melbourne, the prestige venue is known to charge up to $200 a head for special events like weddings.

Last November, the social media star host a post-Melbourne Cup soirée for her attractive gal pals.

Sharing a video of the after party on her new TikTok page, Bec and her friends were seen kicking off their heels and sipping margaritas in her kitchen.

Meanwhile in 2019, the gorgeous socialite and her AFL-star husband, Chris, spent five months organising a lavish housewarming after they moved into their $7.3million home in Melbourne's Brighton.

Dubbing the event 'Juddchella', Bec enlisted the help of one of Australia's top party planners and a team of experts to recreate the Coachella festival in her back yard.

Named after the popular event set in the Colorado Desert, California, the Judd's hired an army of different companies to create 'California valley vibes' across what is usually the couple's tennis court. 

The event was bursting with colour, featuring glitter photo walls, bright furniture, bulb fairy lights, and a designated dance floor with DJ booth. 

Attendees partied from 2pm until 10:30pm, while dancing to music from local DJs. 

Celebrities and WAGS including Nadia Bartel, Kylie Brown and Jessie Murphy completed the star-studded guest list.  

Guests even had access to a glitter station, where they could create headbands and complete their festival look.
