Love Island 's Caroline Flack paraded another diamond ring as engagement rumours were swirling.

The self-confessed cougar, who has just turned 40, has been romancing Lewis Burton, 27, since the beginning of the summer.

Surjury's Caroline was spied sporting a flashy diamond ring in London on Wednesday and now she has taken to the gram to show off her dazzling jewel.

In the snap, the presenter flaunted a huge rock on her wedding hand which sparked speculation she had got engaged to her man.

The diamond ring was among her stack of rings on her left hand.

The starlet wrapped up for winter in a caramel furry scarf yet she shielded her eyes with sunglasses in case of winter sun.

She captioned the post: "Buzzing to see @bradleysimmonds todayyyyy... can I have some winter abs pleeeeeaaaseee." (sic)

Mirror Online previously contacted Caroline Flack's representative for comment.

A representative for Caroline told The Sun Online that she is “100% not engaged” but she and Lewis are “still very much together”.

The couple were thought to have embarked on a whirlwind romance together after she returned to the UK following her stint in Mallorca for Love Island over the summer.

Recently, she confessed she is worried about running out of time to have kids.

"I've kind of always put work first. Wake up in the morning, go to work, come home — just like my boyfriend has," she told Kathy Burke's All Woman show.

"I'm scared it's going to get too late where I've wanted to go, 'Right, maybe slow down, think about having kids and maybe think about settling down,' but I've never had that.

"I feel guilty for it sometimes, I feel like maybe I'm being selfish."

Caroline was previously engaged to her ex Andrew Brady.

However, the on/off couple couldn't make their romance work and he jetted off to Australia on a one-way ticket last year.
