The Scottish fireman was named this year's winner of The Voice UK 2015 after gaining more public votes than opera singer Lucy O'Byrne (4 April).
After the announcement was made, Stevie said: "The hard work starts now... Everybody who has voted for me just go and buy that single."
As he performed single 'Lost Stars' one last time, his wife Amy was seen sobbing with pride as an elated Ricky Wilson - Stevie's mentor - danced about with glee.
The final night fell on Amy's birthday, giving her the BEST birthday gift EVER.
After celebrating his win, an incredulous Stevie turned to Twitter to thank fans.
He wrote: "I am lost for words, I feel like I am in a dream! I'm sorry I nearly broke down singing last song! THANK YOU ALL."
