This is exactly the predicament Prince Harry and Meghan Markle have found themselves in after sharing a candid moment following Liam Payne's performance during Monday'sCommonwealth Day service.

'Let's get checking out an update from MTV News...'

The couple have become unlikely viral sensations after seemingly having a giggle about the moment the former One Direction singer fist-bumped members of his band in the middle of Westminster Abbey.

Casual.

Liam had been looking forward to covering John Mayer's song 'Waiting On The World To Change' and told the BBCthat he felt it was a "super apparent time" to relay the message.

It doesn't look like this unexpected royal reaction has taken the shine off the day, with Liam taking to Instagram after the event to write that he was "honoured" to be asked to perform during the service and hoped people enjoyed his rendition.

"Such an honour to be asked to perform at the #CommonwealthDay service in front of @theroyalfamily! Hope you enjoyed my cover of @johnmayer Waiting On The World To Change," he said.

On the plus side, one person who absolutely loved the performance (fist bumps included) is girlfriend Cheryl, who responded to his social-media post with a singleraised hands emoji.

Can't win 'em all.
