The actor, who will reportedly make a brief return as Ricky Butcher for Janine's wedding later this year, apparently ended his engagement to The Real Hustle star due to their turbulent relationship.
"We're still good friends but we are not together anymore. I'm single," Owen told the Sunday Mirror.
The couple, who met while starring in a Snow White panto in 2006, originally planned to marry in September 2010, but separated for two months after preparations "became too much". They later reunited and rescheduled their wedding.
However, the pair argued over where the ceremony should be held, with Polly wanting to return to Barbados where Owen proposed, and him preferring a French farmhouse.
They had a public fight early on in the relationship, when they were pictured brawling in the street outside an Essex nightclub. Security had to hold Parsons back as she hit Owen with her handbag after a woman in the club chatted him up.
