The Towie stars are on holiday with Joe’s young son from a previous relationship.
Taking to Instagram, Harry posted snaps showing him and Joe looking very happy together.
The couple also posed for a sweet photo with Joe’s little boy as they enjoyed a night out in Tenerife.
After Harry shared the snaps on Instagram, Joe commented: “Never been happier than I am today.”
Harry went public with his new man back in July following a fling with his Towie co-star Junaid Ahmed.
He also revealed plans for the couple to have children together. When asked by a fan, he replied: “I would love children one day! Always said I wanted kids!
“Joe is a dad to [a little boy] and I love him, he’s the sweetest boy ever and love seeing Joe as a dad.”
Harry recently told how he missed out on a Dancing on Ice stint after leaving bosses worried about his body.
He said that his weight had become a ’cause for concern’ at his audition for the show.
The star admitted: “I did [an audition for] Dancing on Ice years ago.
“I went for a meeting but at the time they were concerned because I was underweight.”
