Rare attendee - Though she served as patron of the All England Lawn Tennis and Croquet Club at Wimbledon for over 60 years, the Queen has only attended the tournament four times.

We are not amused - When she attended in 1977, she presented the winning trophy to Virginia Wade (Great Britain), but seemed seriously unamused by the length of the players' tennis skirts.

Unimpressed - Her last appearance was in 2010, when she watched a match between Andy Murray (Great Britain) and Jarkko Nieminen (Finland). The experience didn't seem up to her standards...

Grimace? - Camilla, Duchess of Cornwall, has also been captured pulling some hilarious reactions, such as here in 2011.

Or smile? - It seems as though she enjoyed the match between Venus Williams (USA) and Kimiko Date-Krumm (Japan).

Yet so far... - ...and finally face-palming to show her disappointment.

Worry - Kate and her sister Pippa (left) look tense while watching the 2012 Gentlemen's Singles final between Roger Federer and Andy Murray.

Performance nerves - Even Prince William purses his lips as he watches Murray play. Luckily, the British tennis star came through to win the tournament that year.
