The 18-year-old, who is believed to worked at a Waitrose store in her hometown, is the fourth person to have died at the festival in its seven-year history.
Today, friends paid tribute to the popular teenager who they described as ‘the most funny and amusing person’ to be around. Many said they were ‘in bits’ at learning of her death.
Her best friend, Georgina Hutchins, from Rickmansworth, wrote on Facebook: ‘Words can’t begin to describe how devastated I am and how much I am going to miss you.
‘I will never forget how easily you brought smiles and laughter to any situation even in the worst of times. Not having you here just won’t be the same.
‘I will forever cherish the memories we had together in my heart and you will never be forgotten. You were truly a character. Love you forever and always Liv.’
Another friend, Sophie Cooper, described Livvy as a ‘beautiful person’, adding that she ‘brought so much joy to life and will always be in our hearts’.
Lisa Money, from Aylesbury, worked alongside the teenager and said she was ‘great fun’ and ‘an amazing girl inside and out’.
Meanwhile, Callum Chappell said: ‘Rip Livvy. Honestly the most funny and amusing person to be around, the world lost someone amazing.’
And Lizzie Turner wrote on Twitter: ‘RIP, gone but never forgotten.’
Police said medics were called to a tent at the festival site to treat the unconscious teenager at lunchtime on Monday.
They said she was later pronounced dead at the scene and confirmed the death was not being treated as suspicious. Her next of kin has been informed.
It is the fourth death in six years the controversial festival has faced.
Over the past few years, it has attracted controversy because people lost their lives after taking drugs during the festival.
In 2014, an inquest heard how Lisa Williamson, 31, a mother and beauty therapist, was found hanged in a public loo at BoomTown after taking illegal drugs which ‘affected her state of mind’.
That same year, Hampshire Constabulary seized around 70,000 pounds of drugs and 15,000 pounds in cash under the Proceeds of Crime Act. In 2013, public schoolgirl Ellie Rowe died after taking the horse tranquilliser ketamine at the festival.
The 18-year-old, from Glastonbury, Somerset, was working as a volunteer steward at the festival when she was found collapsed in her tent by a friend.
In 2011, mother-of-two Deborah Jeffery, 45, died from a heart attack at the festival after taking ecstasy.
A statement released by Hampshire Police said: ‘At around midday on Monday, August 15, medics at the Boomtown Fair, Cheesefoot Head, Winchester were called to a tent on site after an 18-year-old woman from Buckinghamshire was found unconscious.
‘Sadly, despite efforts from paramedics and the on site doctor, she was pronounced dead at the scene.
‘The death is not being treated as suspicious but investigations are ongoing on behalf of the coroner.
‘Officers continue to work closely with Boomtown organisers and witnesses and friends who were at the event are being supported.**Next of kin have been informed.’
The death came just days after the festival was rocked by a fire in the car park.
On Friday afternoon, more than 80 cars were destroyed after being engulfed in flames and the campsite was evacuated, although no-one was injured.
Huge plumes of smoke were visible from the site and surrounding countryside during the blaze, which is believed to have been started by a cigarette.
Organisers said their main concern was that ‘anyone affected is safely and swiftly able to get home’.
