Rebecca Judd vomits while trying to eat an axe tongue and bull’s penis with her sister Kate Twigley on The Amazing Race

Rebecca Judd and her sister Kate Twigley was left gagging as they tried to consume a bull’s penis and axe tongue on The Amazing Race.

The WAG, 40, was seen vomiting in a bucket as she tried to eat the tongue while Kate tried to consume the soup during a challenge on the show.

Rebecca shared a photo of herself holding the tongue on a fork to Instagram as her sister had the soup.

‘This episode was wild. A big thanks to my sister for tackling the entire [penis],’ she wrote.

‘This is me with the tongue. And yes I puked half of it up. Loving this journey for us.’

Rebecca is appearing on the show to compete for $100,000 for her chosen charity alongside her sister Kate.

But the glamorous AFL WAG won’t let her standards slip, with an insider claiming that the 40-year-old insists on looking her best despite the sweaty conditions on set.

‘She is there to win and will do anything, but she’s also keeping it showbiz and won’t do anything without makeup first’ the alleged source told Yahoo last week.

‘The crew have been having a laugh, she’s the biggest diva because of how much time she spends on glam compared to the other celebs.’

The insider added: ‘Bec and Kate haven’t been helping anyone and she’s determined to prove to viewers she’s more than just a WAG.’
