Matt Smith from Essex proposed to his long time girlfriend while visiting the Doctor Who Experience. A Message from the 'real' Matt Smith reads.
"Matt Smith proposing to his girlfriend! Firstly, being a Smith means phone calls to the bank take so much longer - there are so many Smiths!! But I bet none of them have proposed at the Doctor Who Experience! Amy and Rory would be proud. Next - babies in the TARDIS...? Congratulations to you both and many years of happiness.Love,Matt.”
By the way she said YES.
