MTV Germany's 'In Touch' show featured an interview with R Kelly in which he sang part of a song that he has written with Whitney Houston in mind. 

Kelly later sang the full first verse and a part of the chorus on Germany's most popular R&B radio: JAM FM.  Here's the lyrics to the part he sang:

After all that we've been through
I look to you, I look to you
Can't hide my feelings
It's still the same
I'm the writer, you're my inspiration
Sometimes the pain
And when all melodies are gone
And you hear this song
I still look to you, I still look to you
