Love Island winners Kai Fagan and Sanam Harrinanan announce engagement in sweet post

Love Island winners Kai Fagan and Sanam Harrinanan have announced their engagement.

The adorable pair first met on the winter series of the reality dating show in March last year, filmed in South Africa.

They won the hearts of the nation and were crowned the winners, beating runners-up Ron Hall and Lana Jenkins.

The happy couple shared the news today (29 April) via a joint Instagram announcement.

The caption, written by Kai, reads: "Introducing the next Mrs Fagan.

"Beautiful, Caring, Loving and Smart are just some of the words that describe you.

"I love loving you, I love you and I can’t wait to spend the rest of my life with you."

The gorgeous engagement photos show the pair dressed in white, with Kai down on one knee and spraying champagne after Sanam said 'yes'.

Adding to the outpouring of love and support, former I'm A Celebrity: Get Me Out of Here! winner Giovanni Fletcher wrote: "Waaaaaaaaaaah!!!! Huge huge huge congratulations! I’m so happy for you!!"

Their Love Island runners up, Ron Hall and Lana Jenkins, have also weighed in.

Ron wrote: "This is the best news EVER! Congratulations you two!"

Lana added: "Oh my god!!! Amazing news congratulations both of you!! So happy for you."

Kai also shared the happy news to his Instagram story, adding that Sanam is his 'whole heart'.

Since winning Love Island, fans looked on in awe as Kai and Sanam's relationship went from strength to strength.

They've shared regular updates to social media, and have taken part in charitable causes, including hosting a raffle and presenting awards for the NSPCC.

The down-to-earth duo recently shared their take on what dates should really be about back on April 19, and it was a breath of fresh air.

Kai wrote: "I feel like the pressures of modern society and social media take away from what a ‘date’ really is.

"It’s not about spending ridiculous amounts of money or doing the most extravagant things all the time. But what it is about is spending time with your person, making experiences and having fun.

"Sanam picked going for a run, I convinced her to come kayaking.

"It’s all about balance."

We are so happy for them, and we can't wait to see the wedding.
