British newspaper The Sun had reported that the 29-year-old was too worried that her summer tour would be a let down - and she might postpone the shows in order to prepare.
A source told the publication: 'Britney has told her management that she wants to push back her concert dates because she's not feeling ready.
'She doesn't feel she has enough time to prepare and has asked management to pull all her dates and postpone everything until later on in the year.
'She's a perfectionist and wants everything to be better than ever before.'
However, a representative for the Till The World Ends singer has since denied this story, claiming the tour isn't going to be postponed.
