The 28-year-old star tied the knot to the 27-year-old stunner at St Mary's Priory Church in Yorkshire earlier this month, and he concluded his speech by performing a tune he had written especially for the former Miss England beauty, who wept throughout the melody.
Introducing his performance, he said: ''Every time I sit at the piano, or guitar, Georgia comes in with her little chocolate voice and goes, 'Is that song about me?' I've actually written a song for you today...' ''
With guitar in hand, the McBusted star sang about how he will still be in love with Georgia when he is ''grey and old'' and how she takes his breath away.
Other guests included boxer Luke Campbell, 'The Only Way is Essex' star Mario Falcone - who is Tom's brother-in-law - and Matt's wife Emma Willis, as well as Dougie's girlfriend Ellie Goulding, who performed a song at the bash.
She was not the only big name to pass on her congratulations to the happy couple as a message from music legend Stevie Wonder was played to the pair during the reception.
He told them: ''I wish you lots of love and happiness.''
The occasion got a bit much for Danny as he admitted he burst into tears when he and Georgia were standing at the altar preparing to say their vows.
Speaking to HELLO! magazine, he said: ''When I saw Georgia, I couldn't really take it. My legs shook. It was the most amazing view I've ever seen.''
But ahead of his speech the star's emotion turned to worry and he could hardly eat the extravagant three-course-meal, featuring ''posh'' fish and chips, because he was the ''most nervous I've ever been''.
The '12 Years A Slave' director will receive the accolade at the London Film Festival in October.
Critics from all over the world were asked to name the best movie of the past 16 years.
