The former X Factor winner announced the news via Twitter on Tuesday (September 25), writing that he was the one to to propose to his partner of nine years.
Ward tweeted: "I have just asked @fayemckeever to marry me and she said.............. YES! X", and accompanied the message with a photograph of the pair kissing.
The 27-year-old recently took on the role of rock star Stacee Jaxx for musical Rock of Ages' London run, but will reportedly be returning to the studio after his contract on the show ended last week.
Ward recently slammed the makers of The X Factor for excluding him from the reality contest's recent TV trailer, featuring the likes of JLS, Little Mix, One Direction and Olly Murs.
He was dropped from Simon Cowell's Syco record label in April 2011 after bosses were allegedly unhappy with the underwhelming sales of Ward's third album Obsession.
