The actor, who has quit his role as Aaron Livesy in the soap after five years, said that he was "absolutely amazed" that co-stars such as Adam Thomas and Kelvin Fletcher went to such an effort to give him a good send-off by making a funny version of the rapper's song 'Written in the Stars'.
Miller told the Manchester Evening News: "Obviously I'd been to Emmerdale leaving dos before, and I knew they always like to spring surprises. I saw them put a TV up, but I honestly had absolutely no idea what they'd been up to. They started telling me that they'd spoken to my girlfriend and asked what my favourite song was.
"They played the video and I recognised the music, but I didn't recognise the start of the video, and then it clicked. It was just unbelievable to think that they'd all gone to so much effort to film the whole thing - I didn't have a clue. And then I couldn't stop crying! I was absolutely amazed by it."
The video shows Thomas, who plays Adam Barton, rapping the start of the Tinie Tempah song in a garage.
Fletcher, who plays Andy Sugden, can also be seen playing the keyboard wearing a curly wig, boxer shorts and Ugg boots.
Miller said: "With Kelvin, when we used to go to the gym together, we'd take the mickey out of him because he'd pop up in the changing room with hardly any clothes on, so I think that was where the joke came from in the video. And the Ugg boots - [it's] because we both wear those too."
He admitted that it will be "nice to be able to take a break" from Emmerdale, but said that he is "already missing the guys" and felt emotional on his last day.
