Elton John posts rare picture of his mini-me son on social media

People can't get over the resemblance.

Elton John gave fans a rare glimpse of his five-year-old son, Elijah, during a concert in Las Vegas last night, when he invited him to join him on stage during the encore. The singer, who recently announced his up-coming 'farewell tour', posted a photo of the moment on his Instagram account, captioning the post: "Elijah joins daddy for the encore." https://www.instagram.com/p/BfSVy-NnjaU/?hl=en&taken-by=eltonjohn https://www.instagram.com/p/BfR3EoxnEVm/?hl=en&taken-by=eltonjohn He shares his two sons, Elijah and Zachary, who is aged seven, with husband David Furnish. It comes after he was also spotted out with them ahead of a Premier League game between Watford and Manchester City last year. Speaking about why he planned to quit touring last month, Elton said it was to spend more time with his children. He said: "I am not going to be touring anymore apart from September, which will be a global tour. My priorities have changed in my life. We had children, they have changed our lives. "In 2015, David [Furnish] and I sat down with a school schedule and I said 'I don’t want to miss too much of this.' The priorities in my life have changed, my priorities are now my children, and my husband. I thought the time was right to say thank you to all my fans around the world globally, and to say goodbye, to have a breather."
