Irish Snapchat star James Kavanagh has paid tribute to his friend Martyn Hett, one of the victims of Monday's terror attack in Manchester.

A suicide bomber detonated a device shortly after the end of Ariana Grande's concert at the Manchester Arena, killing 22 people and injuring dozens more.

Kavanagh has now opened up about his grief at the news that one of the victims was his close friend, 29-year-old PR manager Martyn Hett.

"The world has lost one of its most hilarious and iconic people," Kavanagh wrote on Facebook. "From the moment we met, I knew I struck gold in the friend department. I was instantly in love with him & his equally iconic and beautiful other half, Russell.

"Last night, I went back through our Facebook messages and was laughing and crying at how razor sharp and witty he always was no matter what he was saying to me.

"He was a total joy in my life, and I’m now seeing that he didn’t just light up my life, he enriched and lit up hundreds (probably thousands) of other people’s lives too.

"You’ll always be in my mind Martyn Hakan Hett, you total and utter gas bitch of life. I’m imagining you glugging wine and eating marrow with Deirdre Barlow somewhere. My love and thoughts are with his family, legions of friends & Russell."

The Snapchat star reminisced about they first met in a post on Instagram. They were "internet friends" for about a year before Hett came to visit Kavanagh in Dublin to "turn our internet friendship into a real life one".

"And from there, our relationship blossomed into a joyous friendship and I loved having in my life. We'd talk daily about the hilarity of life - we had a particular love for tabloid photos of reconstructed situations. Out of everyone I know, he lived life to the absolute fullest. He'd make the mundane sparkle. If he's taught me anything, it's that life is for living and to make the most out of everything. You'll be missed, but never ever forgotten." Kavanagh wrote.

Pop icon Mariah Carey also paid tribute to Hett on Instagram after learning that he was a massive fan of hers.

She posted a picture of him wearing a Mariah Carey t-shirt along with the caption: "Devastated to learn that one of the victims in Manchester was part of the #Lambily. RIP Martyn Hett. We will cherish your memory forever. His family and all the families affected are in my thoughts and prayers. MC."
