Look at this year's Love Island and what can you see? That's right, boobs everywhere. But not the top of boobs, as is traditional.

What we're seeing a lot of is a brave new world of boob: the underboob.

What is underboob?

According to the Urban Dictionary (always a reliable source) the definition of underboob is: "Cleavage visible from the part of the shirt that covers the bottom of the female breasts".

Some are calling it ‘the new cleavage’, with the Kardashians leading the way. And we know that any trend with Kylie and Kendall Jenner at the helm is going to be EVERYWHERE.

Whether you love the look or think it’s pretty awful, it looks like it’s a trend that’s here to stay.

In more Love Island related news, Shannon Singh may have only been on the show for three days but she certainly made an impact with the rest of the Islanders.

While the Love Island 2021 cast were in quarantine ahead of their time on the show, Shannon made demands to the producers which made those couple of weeks even better for the rest of her co-stars.

"Quarantine for me was mint. My chaperone was class, I could have happily stayed in quarantine," Brad McClelland explained.

Sharon then admitted, "My chaperone and I got on really well. It was better when we were allowed alcohol. I was drinking alcohol and watching the euros."

But when Brad revealed he was only allowed alcohol a week into lockdown, Sharon explained how it came about.

"That was Shannon. [She] kicked off and was like 'I'm not doing this, if we're not allowed alcohol', so yeah, we were allowed it halfway through."
