The 26-year-old singer - whose real name is Louisa Rose Allen - has made her way into the Guinness World Records book for the string of shows, which she undertook to raise money for cancer charity Trekstock.

The series of seven gigs kicked off at the University of Southampton Students' Union, before she headed to, Brighton, Guildford, Reading, Oxford, High Wycombe and London, travelling between venues in the new Citroën C1, which she claims has encouraged her to pass her driving test.

After breaking the record, she said: ''It's been amazing to see this challenge through to the finishing line. It's been a long day, but I'm so excited to be able to say that I'm now a Guinness World Records title holder. I'd like to say a huge thanks to Citroën and my team for making this become a reality. After taking the New C1 from 'C1ty to C1ty', I'm more determined than ever to pass my driving test and get out on the open road.''

She also tweeted: ''ONLY WENT AND DID IT!!!!!!#C1tytoC1ty one of those wtf moments. Guinness World record done (sic).''

In order to make it into the record books, the 'C1ty to C1ty' shows had to be located a minimum of 50km apart, with each performance lasting at leas 15 minutes.

During her sets, the Grammy Award winner sang fan favourites including 'Youth', 'Glorious' and 'Let Go For Tonight', and was supported by a different up-and-coming act at each venue
