Dancing on Ice winner and 2006 X Factor runner-up Quinn tied the knot with Stephens in a beach wedding in Barbados.
The couple met in 2008 while starring in Grease in London's West End, before getting engaged last February.
Quinn told Hello magazine: "I'm so lucky to have Emma. The dress, I had to catch my breath. I've never seen a more beautiful bride."
Stephens said: "We're deeply in love and having a baby together feels so right.
"I saw other holidaymakers watching us - they gave us a round of applause. In his speech Ray vowed, 'I'm going to look after you forever and can't wait to spend the rest of my life with you'. That really choked me up."
