One of the original contestants has announced she's pregnant.

Hannah Elizabeth shared a photo of her growing bump on Instagram as she posed in her underwear.

She rose to fame on the 2015 series and was briefly engaged to TOWIE's Jon Clarke, who she met on the ITV2 show.

The pair's summer romance only last a few months after filming and she went on to find love with Youtube star George Andreetti.

Hannah and George got engaged during a sunny beach holiday in March 2018.

Fellow Love Islanders rushed to congratulate the couple on their happy news.

2017 islander Tyne Lexy Clarkson wrote: “Oh my god” alongside four red love hearts and fellow reality TV star Vicky Pattison commented: “Congratulations gorgeous girl”.

George reshared Hannah's pregnancy snaps to his own Instagram page shortly after she broke the news on Monday night - just two weeks before a new series of the ITV2 dating show begins.

He told his 13,000 followers: "The secrets out and I'm so happy and grateful not long now and thank you everyone for your kind messages."

It's the second Love Island pregnancy to be announced this month - Jessica Shears announced she was expecting her first baby with husband Dom Lever, who she met on the show in 2017.

The couple shared a picture of their sonogram along with a snap of Jess' baby bump.

The picture also showed Dom, 28, cradling his own tummy as he imitated his wife's pose.

Mum-to-be Jess, 25, wrote: "The best is yet to come."

Dom also shared the picture, adding: "Living the dream ."

The new series of Love Island 2019 will air on ITV2 at 9pm on June 3, 2019.
