Well my source is
wiwibloggs, but her statements contradict tbh.
“There is so much to start again, and then I need a new song that I really love. I have worked so damn hard for this, I have invested all of the work and money into this," she says, which suggests that the reason she won't take part in the final of next MGP is that she needs a song she really loves and going through same phases will be stressful/difficult or w/e.
But then again, she says “I had a dream that they would send me next year, but that was not the case. I am very sorry and disappointed with that decision, but that was the way it was.”
So, if it wasn't for the MGP final but instead an internal selection, she would magically have all the reasons to produce a song that she really loves and she suddenly would be able to go through all the stress again?
Lol, I am glad Norway won't send her internally again.
