And Spice Girl Emma, 39, who got engaged to Jade in 2011, insists they're in no rush.
Speaking to OK! magazine, Emma said: "W're both Aquarians and we're a little disorganised, so we never get round to organise anything!
"We're happy the way we are. We've got our babies, we're engaged, our relationship is secure, so we haven't really thought about it. I'm sure we'll be one of those couples that elope somewhere."
Emma also revealed that, for now, she's happy with the two children she's got, despite previously saying she'd love another before she's 40.
She and Jade are parents to sons Beau, eight, and three-year-old Tate.
"My youngest is only three, so I'm really enjoying this moment and I'm not thinking about another child yet," she continued.
"Jade would definitely have loads more! He's an incredible dad, so hands-on."
It seems like Emma and Jade's carefree attitude to marriage is working for them: 17 years is like a lifetime when it comes to celebrity couples!
