A Reddit user has shown how not to try and take a picture of a famous celebrity.

Reddit user PM_Me_Yer_Guitar recently shared a photo of his brother in a restaurant with Sir Elton John in the background.

However, it seems that the singer was more than aware he was being photographed, judging from the cheeky grin on his face.

Fellow Imgur users questioned the validity of the photograph, as many believed it may have been one of the legendary singers countless lookalikes.

But judging from Sir Elton’s recent holiday snaps at a ski resort with his family, it seems the photo may indeed be of the singer, as many others in the image are also wearing ski gear.

The veteran singer and his partner David Furnish recently celebrated the ten-year anniversary of their civil partnership recently.

The pair were the highest-profile couple to enter an early civil partnership, holding an extravagant reception after registering on December 21 2005 – the first day that civil partnerships existed.

The couple would later convert to a marriage on the same date nine years later, effectively backdating their marriage to 2005.

Sir Elton took to Instagram to celebrate his double anniversary.

He said: “Ten years ago today, we were one of the first couples to embark on a Civil Partnership in the UK. One year ago today, we renewed our lifetime pledge to each other by getting legally married.

“Today, we are happier than ever – and want to thank fans and friends for supporting us with such open hearts and joyful spirit.

“We also want to shine a light on all the less privileged and less advanced parts of the world, where LGBT people are criminalised and discriminated against.

“We pledge our support and will continue to help wherever we can.”

Ten years on, the pair are continuing their work to advance LGBT equality around the world.
