One fifth of the world's biggest boy band and funny man James lock lips on his TV show A League of Their Own while fellow 1D members Louis Tomlinson and Niall Horan watch on.
The second episode of the comedy panel show sees 19-year-old Harry walk over to where James is sat and perch on his knee.
Amid lots of laughter, the pair lock lips in a friendly embrace.
After sharing their romantic moment, Harry joins his bandmates Louis and Niall to take part in a game of 'Popstar Penalties'. The fun-loving trio take turns in goal and allow their pop star elders including Sinitta and Blue's Simon Webbe to take penalties against them.
More fun and frolics are to be had on the show when Harry takes part in a game of basketball – if he misses the hoop, he is submerged in a tank of water as a punishment.
Given that Harry's 'twerking' video from the Teen Choice Awards last week amassed 200,000 views on YouTube, it's certain that scores of adoring fans will tune in to watch Harry and James' special moment unfold.
It isn't the first time that James and Harry let the world know how much they enjoy one another's company, despite their 15 year age gap. The duo famously enjoy a fun friendship and are often spotted together both onscreen and offscreen.
