I don't know if I'm being slow or the article is poorly written but it's confusing.
What I got from it was:
- Ke$ha sent a text to Lady Gaga
- That text was added to the evidence for the case
- Ke$ha was ordered to share the text with Dr. Luke (it sounds like he never saw it before, he just knows that it was sent)
- The text has been sealed by a judge but Dr. Luke has permission to share it with Katy
