The 'Bleeding Love' singer's third studio LP will be available on March 26, 2012, according to Amazon.
This means Glassheart has been delayed by four months, having originally been earmarked for November.
The 26-year-old announced on Twitter earlier today that her LP would be delayed until 2012.
She has previously expressed her concern that her record label Syco is "scared" about Glassheart's experimental sound.
