With no plans to return to his day job, the 23-year-old former Social Media Marketer has joined Cameo, offering fans videos with a personal message.

Irish stars using the site include Jedward (€147), Jason Byrne (€49), Samantha Mumba (€64) and Nicola Coughlan (€294).
Making the best of his time since leaving the ITV show, Jack was spotted getting cosy with fellow Casa Amor bombshell Coco Lodge.
The pair were pictured walking hand-in-hand while another showed Jack with his hands around her waist.
Coco and Jack were both brought onto the show as bombshells for the Casa Amor challenge, which saw the girls travel to a new villa to spend time with new boys while the original boys got to form connections with new girls in the main villa.
After leaving the show, the Dubliner admitted he really enjoyed his time on the show, despite not finding a romantic connection.
"I went in there and was myself and I wore my heart on my sleeve and I have no regrets - I absolutely loved it," he said.
He added that leaving was "bittersweet" because his time went by so quickly.
"I met some great guys and it was nice getting to know the girls. It just went up a bit too fast. As we were getting into it, it wrapped up. But I had a really great time, a great couple of days so no complaints!"
He said he was "nervous as hell" before walking into Casa Amor.
"Just before I walked in I felt fine but as soon as we sat down and started chatting to everybody I was like ‘oh my days- I can’t believe I’m here.’"
He wasn't too surprised that he didn't end up going into the villa.
"I just went with the flow at that stage. I wouldn’t say it was a shock, I wasn’t 100% convinced I was going back to the villa but it was hard to tell."
Dubliner Dami Hope and his girlfriend Indiyah Pollack came fourth on the show, while fan favourites Ekin-Su Cülcüloğlu and Davide Sanclimenti won the show by a landslide of 63.7% of the public vote.
