Janet Jackson has written an open letter to the late r 'n' b singer Aaliyah on the 14th anniversary of her death.

The young singer was killed in a plane crash, along with 8 others, in August 2001 upon returning from a video shoot in the Bahamas. The unlicenced pilot was later found to have traces of cocaine and alcohol in his blood.

Jackson posted the note on Twitter, which read "What I shared with u [is] ever sacred, everlasting [and] it's pure and it will endure. I love u Aaliyah. #RIP."

Timbaland recently revealed that he plans to share previously-unheard material by Aaliyah at some point in the near future.

Jackson, meanwhile, releases her new album 'Unbreakable' in October.
