We can't believe there will never be another new Whitney Houston song ever released after this...

The late singer's final song "Celebrate", a duet with Jordin Sparks for the movie Sparkle, was released this week and unveiled on Ryan Seacrest's radio show Monday. The tune was produced by R&B powerhouse R. Kelly and will be available June 5 on iTunes.

Sparkle was the "Greatest Love Of All" singer's last project before her Febuary death at the age of 48. The film is a remake of the 1976 movie, and will also star Cee Lo Green, Mike Epps, and Derek Luke. Houston will play Sparks' mother.

This past weekend the Billboard Music Awards honored the Grammy winner with a posthumous Millenium award, which her daughter Bobbi Kristina accepted in her honor.

We will always love you, Whitney!
