The Britain’s Got Talent judge hilariously participated in the viral challenge on her morning show alongside her hilarious co-host Ashley Roberts.

The Pickle Trend is where people try huge packaged pickles for a snack and Amanda got into Van Holten’s Hot Pickle on the air Wednesday morning.

Amanda seemed to be enjoying the challenge as she made a very cheeky comment while sampling the pickle while joking that she was “used to the bigger ones.”

Before trying the sandwich, he said, ‘It smells amazing… I’m going to drink the pickle juice.’ She tastes a bit like the sea but with chilli. Now let’s take a look at this baby.

To which Ashley replied, ‘Wow! That’s one big pickle potato! Oh my gosh, honey, that’s big.’

And Amanda replied, ‘I’m used to the bigger ones, I’m going to say… Oh my gosh, it’s beautiful. I like it a lot.’

The Pussycat Doll singer added: “I feel like you’re really enjoying this Amanda.”
