There's been some dismal spring weather over the past few weeks.

But McFly frontman Tom Fletcher was thrilled today when the sun finally came out for his romantic wedding to childhood sweetheart Giovanna Falcone in central London.

The singer, 26, and his actress bride, 27, tied the knot at One Marylebone, a 19th century, Grade I listed former church built by acclaimed architect Sir John Soane.

Pretty in pink: The bride's younger brother Mario Falcone arrived with his girlfriend and Only Way Is Essex co-star Lucy Mecklenburgh

Supporting the couple were Tom's McFly bandmates Harry Judd, Dougie Poynter and Danny Jones - who are all best 'men' - and Giovanna's parents Mario Snr and Kim and siblings Mario and Giorgina - who have all appeared in The Only Way Is Essex.

Also at the wedding were the rest of McFly's girlfriends, model Georgia Horsley (Danny's), artist Lara Carew-Jones (Dougie's) and Escala violinist Izzy Johnston (Harry's).

TOWIE star Mario Jnr arrived with his girlfriend Lucy Mecklenburgh, who was wearing a fuchsia 'Renee' dress from her Love Lucy X fashion collection and a pair of towering nude Christian Louboutin heels.

Although the bridal party and guests were photographed outside the building, the bride and groom were kept away from the cameras - presumably to protect an exclusive magazine deal.

Under wraps: Security men kept the cameras from getting a proper glimpse of the bride, who arrived in a white taxi with her father Mario Snr

Waiting for the bride: Giovanna's bridesmaids were wearing dusky pink asymmetrical gowns

While the bride was kept under wraps by umbrella as she exited a black and white vintage car, the bridesmaids were seen waiting for her in their pale pink dresses.

Ahead of the ceremony, Tom was joking about on Twitter that he wasn't sure what his plans were for the day.

He said: 'I'm sure I'm meant to be doing something today.'

His fiancée was quick to retweet his comment, and joked: 'Naaah! Just your average boring Saturday! Xxxx.'

At 11am, he wrote one last Twitter message before heading off to the ceremony: '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...'

Giovanna's younger brother Mario, 24, was clearly excited about formally welcoming Tom to his Anglo-Italian family.

He tweeted: 'Off to my sister and @tommcfly wedding... What a beautiful day for a beautiful couple! Love them both so much.'

Mario's girlfriend Lucy Mecklenburgh, 20, added: 'Off to @giovannafalcone & @tommcfly wedding! What a beautiful day .. Gi is going to b the most stunning bride :-) xxx.'

Aside from the TOWIE couple and McFly bandmates, Inbetweeners star Joe Thomas and his actress girlfriend Hannah Tointon, TV presenter Fearne Cotton and boyfriend Jesse Wood.

The couple first met when they were 13 when they were pupils at the Sylvia Young School and started dating eight years ago.

Tom proposed to Giovanna at the school in April 2011 after he lured her there under the pretence he was filming a documentary about his life.
