Tulisa parties in Ibiza, cancels festival appearance. Eek.

After her sex tape drama came to a close last week, with Tulisa's ex boyfriend admitting he leaked the footage,  Tulisa announced outside the court that she was jetting off to Ibiza.

However, Tulisa was supposed to make an appearance at Guilfest festival yesterday - but cancelled half an hour before she was due on stage, because she was ill. Oops.

Tulisa took to Twitter to announce the news, telling fans she was 'gutted' to miss the show.

The organiser of the festival revealed: "We got a message from Tulisa's team just beforehand saying she was unwell and could not make it.

"They said she was really sorry and would love to come back next year. I think she was genuinely upset at not being able to perform but if somebody is not very well, they are not very well. You have to be 100% when you get up on the stage."

Here's hoping Tulisa's feeling a bit better now.
