The British star kept the rest of her red carpet look relatively simple, accessorising with a dramatic silver disc statement necklace, and toting her belongings in a small red and gold clutch bag.
Showing off her naturally striking features with natural make-up, the mother-of-one wore her long honey blonde locks tumbling in loose waves around her shoulders, and appeared to have opted for an unusual pinky hue for the occasion.
The 27-year-old actor completed his look with smart black leather shoes and a black felt fedora as he wrapped a protective arm around the waist of his wife-to-be.
It would appear the Broadway star had been taking part in 'Movember', and was sporting a significant amount of facial furniture in the form of a perfectly-coiffed moustache as the cute couple took to the red carpet.
And the pair have become key players in the fashion world since being announced as the new faces of iconic British brand Burberry earlier this year.
Speaking about the AW'13 shoot, which was shot by Mario Testino, Burberry Chief Creative Officer Christopher Bailey said: 'This was a shoot full of love and laughter.
