Ke$ha has commented on her track 'Die Young' in the aftermath of the recent school shooting tragedy in the US.

As previously reported, her single was removed from playlists on certain radio stations in America after the country was rocked by news of a gunman killing 20 children and six adults at a school in Connecticut.

20-year-old Adam Lanza gunned his victims at Newtown's Sandy Hook Elementary School on December 14 before killing himself.

Taking to Twitter to comment on the ensuing controversy surrounding 'Die Young', Ke$ha said:

"I'm so so so sorry for anyone who has been effected by this tragedy and I understand why my song is now inappropriate. Words cannot express."

It has been reported that the singer added another tweet implying that she was "forced" into singing the song's lyrics, before deleting the message. It is said she tweeted: "I understand. I had my very own issue with 'Die Young' for this reason. I did NOT want to sing those lyrics and I was FORCED TO."
