Lions centre Manu Tuilagi has apologised on Twitter after making a 'bunny ears' gesture behind the British Prime Minister David Cameron.
The British and Irish Lions squad visited Downing Street on Monday for a reception to celebrate their 2-1 series victory over Australia earlier this year.
Several of the squad's stars who are now based in France were absent, including scrum-half Mike Phillips.
Tuilagi gave Cameron "bunny ears" as the squad and management posed for a photo on the steps outside the Prime Minister's official residence in London.
Commenting on Twitter afterwards, the Leicester and England back apologised for his actions.
"Apologies for messing around on Lions photo. No offence intended. Great Day at Downing Street. Thanks to Prime Minister for hosting us," said Tuilagi.
Tuilagi famously was fined after jumping off a ferry during England's 2011 Rugby World Cup debacle two years ago, when he was forced to pay £3000 by the RFU.
