"Apologies for messing around on Lions photo. No offence intended," Tuilagi said on Twitter. "
Great day at Downing Street. Thanks to Prime Minister for hosting us."
The British and Irish Lions were invited to the Prime Minister's official residence on Monday to celebrate their 2-1 series win over Australia in June and July.
Samoan-born Tuilagi, 22, ran into trouble two years ago when he jumped from a ferry during the World Cup in New Zealand. He was fined £3 000 by rugby officials and cautioned by police.
