The McFly rocker and Giovanna Falcone have been together for eight years, and got engaged in April last year (11).

The pair is set to wed in front of friends and family, including Fletcher's bandmates Danny Jones, Harry Judd and Dougie Poynter, who will all act as Best Men at the ceremony in London's Marylebone on Saturday.

An ecstatic Fletcher took to Twitter.com to tell fans of his excitement, writing, "Ok, this is probably my last tweet for today. The next time I tweet I will be a married man!... unless giovannafalcone stands me up..." (c) WENN
