British pop star Tom Fletcher will walk down the aisle with his longtime girlfriend on Saturday.

An excited Fletcher wrote on Twitter, "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..."
 
The McFly rocker and Giovanna Falcone have been together for eight years and got engaged in April 2011.
 
The couple 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.
