'My biggest secret is who Love Story is about... I'll never tell!' Handwritten notes written by teenage Taylor Swift sell for £14,200 at auction

Handwritten notes written by a teenage Taylor Swift have sold for £14,200 at auction, including answers to a questionnaire.

When she was 19-year-old, the singer filled out a questionnaire for MIZZ Magazine in which she revealed insecurity about her looks.

The two pages, which sold at a Bonham's auction in London on Wednesday, saw the teenager write: 'If I could be someone else for a day I'd be.... Rachel McAdams or Miranda Kerr. I wonder what it's LIKE to be that pretty.'

When asked what her biggest secret is, she replied: 'My biggest secret is...Who the song 'Love Story' is about. I'll never tell!'

The singer also seemingly sketched a stick-figure doodle of a girl with a guitar and a speech bubble that reads: 'I like to write songs about boys'.

Bonham's said: 'In August 2009, the vendor who was working for MIZZ Magazine as a features writer met Taylor Swift and her mother in London at her hotel. 

'The vendor asked her to sign her copy of MIZZ Magazine which had Taylor on the front cover. She also asked her to fill in the questionnaire for a future issue.'

The auction house say one question regarding 'Who would Taylor rather kiss' has been crossed out in black ink by Taylor's mother having reviewed the questions ahead of their meeting.

The names Taylor Lautner, Joe Jonas and Zac Efron are visible underneath the censored men.

The questionnaire had been estimated to fetch £2,000 - 3,000.

Taylor's answers include: 'My proudest moment was... When every show on my first headlining tour SOLD OUT this year and being on the cover of Rolling Stone.'

'If I could be someone else for a day I'd be... Rachel McAdams or Miranda Kerr. I wonder what it's LIKE to be that pretty.'

'I can't live without...'My guitar'

'My fans are...The most beautiful, dedicated, creative hilarious, sign-making, dress-wearing, wonderful people. I adore them.'

Earlier today, it emerged her fans caused such a stir at her Eras Tour gigs in Scotland over the weekend that seismologists recorded tremors nearly four miles away.

Some 220,000 people turned out to see the American pop icon at the Murrayfield Stadium in Edinburgh between Friday and Sunday, averaging 73,000 each night.

And as the 34-year-old headed north for her UK dates, Swifties showed their appreciation by dancing and stamping loud enough for the British Geological Society to pick up minor movements on the ground.

'If you can imagine, you have 73,000 people in one concentrated place — jumping, clapping, dancing,' said Sophie Butcher, an Edinburgh volcanologist who was in the crowd on one of the dates.

'As well as that, there's a big bass sound system. All of that energy travels through the ground,' she said, as reported by The Times.
