Prince William's mother Diana was always keen on making sure her boys took part in the same kind of pastimes as normal members of the public.
Eating in fast food restaurants or paying a visit to a theme park were just a couple of the activities Wills and Harry got up to when they were youngsters.
And following her desires for his upbringing, the royal and his long-term love Kate Middleton ventured out to watch a romantic comedy at a West London cinema this week.
Joining spectators at Heather Graham's flick The Hangover, the Prince and his brunette love sneaked into the movie theatre, wearing jeans and baseball caps.
"No-one expected royalty but they acted like normal people off the street,” said a fellow cinema-goer.
"It was dark so not many people had any idea who they were. I think they liked the anonymity.”
