Adele swore 33 times during her 90-minute Glastonbury set.

Adele's much-discussed performance featured a swear word ever 2.7 minutes, according to MirrorOnline, and the award-winning singer could not even get through her first song of the evening before she dropped an F-bomb.

Prior to finishing her hit single 'Hello', Adele told the crowd: "You are f**king amazing!"

Later, Adele added: "Oh my God. Oh my God. Hi. This is the best f**king moment of my whole life. Oh my God. Look at you. Can you put the lights on [the audience] more? I want to see them."

During her set, Adele - who is well-known for her use of expletives - revealed that the BBC, who were broadcasting the event, had warned her to control her language before she took to the stage.

She shared: "The BBC had to give me a warning about my potty mouth."

And Adele then said that another of the festival's headline acts, Muse, are unlikely to have been given the same advice.

She quipped: "I bet Muse didn't get that!"

While Adele's set drew a generally positive reaction from fans and critics, her expletive-riddled statements proved to be rather more controversial, with lots of fans taking to social media to voice their disapproval at her course language.
