The McFly drummer tied the knot with long-term girlfriend Izzy Johnston on 21.12.12 at the St. Nicolas church in Harpenden, Hertfordshire, East England, in front of guests including bandmates Tom Fletcher, Danny Jones, and Dougie Poynter, former Busted star Matt Willis and his presenter wife Emma, and his `Strictly Come Dancing` pal Robbie Savage.
Following the ceremony, the guests departed for the reception in a red bus, though it is unclear where the celebrations continued.
Harry, 26, and Izzy - who have been together for seven years and got engaged in May - were also greeted by fans waiting outside the church after the ceremony.
However, other supporters of the group took to Twitter to condemn them for being "rude and selfish".
One fan wrote: "I can`t believe `fans` are waiting outside the church at Hizzys [Harry and Izzy`s] wedding. That is rude and selfish, give them some privacy."
It was also claimed other fans had shouted abuse at former Escala member Izzy, prompting one Twitter user to post: "Hate to break it to you but you never would have stood a chance with Harry anyway, so hating on his wife to be is seriously low. Be happy."
