The pair were dining at Millie's favourite restaurant when her long term boyfriend popped the question!
Naturally a very happy Millie shared the news with her fans!

The couple, who've been dating for over a year, went public with their relationship at the BRIT Awards in February 2011.
Congratulations to the happy couple!
Are you excited to see the couple's wedding photos?
