Prince Harry enjoyed a catch up with the man often referred to as his "second father" over Christmas.
Prince Harry
The 32-year-old royal - who is currently dating 'Suits' actress Meghan Markle - was spotted having a few drinks with his close pal, former Army officer Mark Dyer, at Mark's pub in London.
A source told MailOnline: "They had their heads down most of the time as if they really wanted to keep their chat private.
"They laughed and joked a bit, like they were old mates. Harry's bodyguard was also on the table as they talked.
"When Harry left he thanked the bar staff and was very polite."
Harry brought Meghan to the pub, the Sands End in South West London, during her last visit to London.
Mark was an equerry to Prince Charles at the time of the death of Princess Diana and Charles asked Mark to look out for Harry and his brother Prince William.
Since then, Mark has remained close to both Princes and was one of the guests at William's wedding to Duchess Catherine.
Royal biographer Penny Junor previously wrote in her book 'Prince Harry: Brother, Soldier, Son': "Mark Dyer is incredibly good for him because he's one of the few people who talks some sense into him at times."
