In extra footage of the ITV reality show, which aired on spin-off show Extra Camp, Roman revealed details of a water fight between him and the royals. \”One time I had a letter through and it was from Prince Harry to come and DJ at the Buckingham Palace garden party,\” he told fellow campmates James Haskell and Ian Wright. \”I was playing a track and someone came over and said, \’Roman come here\’, and it was Prince Harry.\” The 26-year-old was invited to DJ at the royals\’ charity bash after meeting the three royals during a live radio chat about mental health.

\”Princess Kate was there and there was a slingshot in the middle,\” he added. \”They\’ve got a bucket filled with water balloons, and they\’re just pinging off these water balloons into the crowd from a balcony.\” However, Roman went on to explain how Prince Harry urged him into firing a water balloon at his older brother, to which he said: \”I\’m like, \’what is going on?\’ [Harry] said, \’aim a bit to the left\’ and I said, \’who am I aiming for?\’ and he said, \’my brother!\’ I said, \’no I\’ll be done for treason!\’\”
