The 21-year-old actor, who has won awards for his portrayal of the angst-ridden Aaron Livesy, made a stirring statement on Twitter.
"Well that's it," he wrote earlier this evening (Friday). "Can't explain the emotions i feel at the moment!
"It's been a pleasure to play Aaron and I love you all for taking the character on and loving his storylines. Thank you so much for your support for me the last 4 years!
"I love you all and finally a HUMUNGOUS thank you to everyone at Emmerdale for the trust and support me like families do! Thank you all so much! X"
Yesterday, a report revealed the location and possible nature of Aaron's final episode, which will air on April 5.
Over the next fortnight, the character becomes romantically involved with a professional rugby player called Ed.
Emmerdale bosses have already confirmed that Aaron's exit will be "heartbreaking".
