One of the defining characteristics of the relationship of Prince Harry and Cressida Bonas has been the extraordinary lengths the couple have gone to in order to avoid being photographed together.

However, over the last few days the young royal and his girlfriend have been out and about together in full public view in London, making the most of their last few days together before Harry heads off to Australia on official duties, representing his grandmother at the Aussie equivalent of Fleet Week.

The couple were pictured together leaving the Prince of Wales Theatre in London's West End after watching the musical 'The Book of Mormon.'

It was the second time the pair had been out this week, as on Monday evening they were spotted leaving a James Blunt concert at the Tabernacle in Notting Hill.

Their willingness to be seen together in public has increased speculation among Harry's set that Cressida may be ready to "go public" as Harry's girlfriend - something that has never been officially confirmed - which could in turn be a first step to an engagement.

Friends of the young royal have told the Royalist that Cressida is 'definitely the most serious relationship' Harry has been involved in since he broke up with Chelsy Davy.
