Jordan Banjo had planned to propose before his girlfriend fell pregnant again.
The Diversity dancer and his partner Naomi Courts - who already have eight-month-old Cassius together - were shocked when they recently found out they were expecting their second child, and the 26-year-old star admitted the happy news has made him put wedding plans on ice.
Asked if marriage is on the cards, he said: "That's definitely what I want.
"I was hoping to propose before Naomi fell pregnant again but things haven't worked out that way. It's next on our agenda."
Naomi, 27, added: "He's got my ring size and knows what I like, so there's no excuse now.
"He just needs to find the time!
"I want to be married by the time I'm 30."
While Naomi's second pregnancy wasn't planned, the couple are much more calm this time around.
She told the new issue of OK! magazine: "We're definitely more relaxed.
"When I first had Cass, I questioned everything - why is he crying? How do I know if he's hungry? Am I doing this right?
"This time, I feel confident enough to go with the flow a bit more."
The couple will find out the sex of their baby later this month but the "Greatest Dancer" host has already been shortlisting names - though he doesn't think his girlfriend will approve of his choices.
He said: "With Cassius, we knew we wanted a strong, unusual name but we didn't want anything too mad.
"I've got a few ideas but they're all inspired by "The Avengers" so I don't think Naomi is going to let me get away with them.
"Cassius and Iron Man has a ring to it, don't you think?"
