The singer was due to make an appearance in Ireland today (July 12) and play the Kinross site tomorrow (July 13) but has cancelled both performances.
Writing on her Myspace page, the singer said: “Hello from rainy Stockholm. So it seems I’ve got acute lymph something something.
“It’s nothing too serious, but I’ve been ordered not to move. Apparently there are ‘stress and toxic symptoms’, but I don’t feel stressed, just fucking painful.”
She added: “The really bad part is that I’ve had to cancel T In The Park and Oxegen. Sigh. Really sorry about that. Seems that two years of non-stop touring have finally caught up with me. But I’ll be back fighting fit before you know it.”
Liam Finn is now due to replace Maria on Oxegen‘s 2FM New Band Stage at 7.15pm (BST) tonight.
