Twitter was set alight on Sunday evening, following news that Taylor Swift will be Glastonbury 2020's Sunday night headliner. Paul McCartney and Diana Ross are already lined up to play the festival's highly anticipated 50th anniversary.

Sharing the announcement on her own social media accounts, Swift revealed that she's "ecstatic".

The official Glastonbury Twitter account was also "delighted" to share the news, describing the American pop sensation as "one of the biggest stars in the world", whose songs "are absolutely amazing."

"She’s one of the biggest stars in the world and her songs are absolutely amazing. We’re so delighted.”

The announcement comes at the end of a triumphant decade for Swift. Hot Press's Edwin McFee noted that her seventh studio album, Lover, released back in September, "may perhaps mark the end of phase two of the Taylor-verse (ie the one where Swift transitioned from talented country queen to super slick, all-conquering pop star)".

"If Lover does mark the closing of that chapter in her life," he continued, "she's certainly finishing it with a bang."

Her very own documentary is also on the way. Taylor Swift: Miss Americana, set to premiere at the Sundance Film Festival in 2020, is described as "a raw and emotionally revealing look at one of the most iconic artists of our time during a transformational period in her life as she learns to embrace her role not only as a songwriter and performer, but as a woman harnessing the full power of her voice."

Her Sunday night slot will also make her the sixth solo female artist to headline the festival, following Suzanne Vega, Sinead O'Connor, Kylie Minogue, Beyoncé, Adele and Taylor Swift.

Thousands of Swift's mega-fans took to Twitter to share their excitement about the announcement. Journalist Nick Levine described her as "an incredible booking" – comparing her to Kylie Minogue, who performed this year.

PinkNews editor Ryan John Butcher stated that the pop star is "at the zenith of her career", and described her as "the perfect tonic for broken Britain" – "and, more importantly, she's fucking earned it".

However, not everyone was happy with the announcement. Several Glastonbury-goers took to Twitter to express their disappointment with the festival's choice of Sunday night headliner.

My first year and so far we have McCartney Diana Ross and frickin Taylor Swift. Where the proper modern rock?! Very disappointed. Some serious making up to be done.

Taylor's fans were quick to put the naysayers in their place.
