Rebecca Judd reveals her favourite cheat day fast food meal and it may surprise you

Rebecca Judd took to social media on Tuesday night to reveal her go-to fast food meal, and it may surprise many of her fans.

The AFL WAG, 41, shared a video to Instagram where she was seen unwrapping a Whopper from Hungry Jacks.

'I've always said that the burgers are better at Hungry Jacks. This is my one, a whopper with cheese minus onions,' Bec began.

Bec was then seen grabbing some fries.

'Their chips are better, too. I didn't realise this until tonight, they are definitely better,' she added. 

She pledged her allegience to Hungry Jacks in the comments: 'HJ's > KFC > Maccas.'

The super fit model has previously told fans she often indulges in fast food as a treat.

The mother-of-four appears quite relaxed when it comes to food, and recently indulged in a variety of meals during a luxurious holiday with her AFL star husband Chris Judd.

Bec showed off her slender frame in a video shared to Instagram as she revealed her 'day in the life' during her stay at Bawah Reserve - a private island resort in Indonesia.

In the video, Rebecca revealed she starts her day with a cup of coffee before going to a yoga glass.

She then had a long macchiato and enjoyed an omelette for breakfast.

After going for a swim, Rebecca had a delicious crispy fish burger for lunch before going for a one hour massage and drinking a ginger tea.

For dinner, Rebecca had gnocchi while her husband Chris opted for prawns and lamb shanks.

Bec burst onto the scene at age 21 when she wore a red dress with a plunging neckline to the 2004 Brownlow Medal alongside Chris.

The outfit, which boasted a neckline that dipped below her belly button and a daring thigh split, was created by Perth designer Ruth Tarvydas, and was valued at $2,000.

Chris and Bec tied the knot in 2010 and they now share four children - daughter Billie, nine, son Oscar, 12, and twins Darcy and Tom, eight.
