RANGERS fans have been captured on camera belting out the sectarian 'Billy Boys' song in an OFFICIAL Florida Cup video.

The footage was poted by organisers on their YouTube channel and it shows a small group of supporters clearly signing the song while the TV presenter unwittingly dances along to it.

Rangers are currently taking part in the event in America and a sizeble group of fans have travelled to the US to watch their Ibrox side.

Rangers fans sing 'Billy Boys' song in official Florida Cup video

Under anti-bigotry laws the sectarian song is banned in Scotland.

It was also outlawed by Rangers in 2006 after the club was slapped with a £13,300 fine from UEFA after it was sang during a Champions League clash with Villareal.

Last year French club Marseille also made a social media blunder when they quoted the song by posting  “Hullo hullo” alongside a picture of Ibrox stadium as they prepared to face the Light Blues.

The clip was posted online just after Rangers beat Atletico Mineiro 1 – 0 in the Florida Cup earlier this week.
