Jesy Nelson and Jake Roche are planning a "white wedding with all the trimmings".
The couple only got engaged last month but have already started planning their nuptials and the Rixton frontman's mother Coleen Nolan doesn't think they'll wait too long before tying the knot.
Coleen said: "They definitely want the whole hog, a white wedding with all the trimmings.
"And although they're young, I don't think they'll hang about."
Little Mix singer Jesy has begun thinking about her dress and emailing her future mother-in-law about her ideas.
Writing for the Daily Mirror newspaper, Coleen added: "Jesy has been emailing with dress ideas ranging from fishtails to princess skirts."
Jake, 22, popped the question with the aid of friend Ed Sheeran after Little Mix finished soundchecking at Manchester Arena, but Coleen says the 'Me and My Broken Heart' hitmaker initially had a number of other ideas of how to propose.
She added: "We were all in on the secret.
"He ran lots of ideas past me but decided in the end to get down on one knee during the soundcheck, and got his mate Ed Sheeran to serenade them.
"Afterwards, we all went back to mine and the table was immediately covered in bridal magazines."
