Danny, 27, popped the question with a diamond ring last night (25 July) and was delighted when Georgia, 26, agreed to be his wife.
The singer shared his exciting news on Twitter alongside a cute photograph taken moments after the proposal.
Alongside the photo, Danny - who has been dating Georgia since 2009 - tweeted: "The future Mrs J yeahhhhhhhh!!!"
In the snap, the couple are beaming from ear-to-ear as model Georgia shows off the gorgeous sparkler now adorning her wedding finger.
Following the announcement, Danny's bandmate Tom Fletcher was quick to congratulate him on his engagement.
Tom, who married wife Giovanna last year, tweeted: "Super massive congratulations to @Dannymcfly and @GeorgiaHorsley1 on your engagement!!!!! Bloomin awesome news!!!!!"
