From one singing sensation to another, Natalie Cole and Paula Abdul sit down for an intimate chat on the ET stage to talk about all things music -- including Natalie's new album Still Unforgettable!

While Natalie calls her new album "fresh and flirty and fun" she adds that after a long break it was finally the right time to come back onto the scene.

"It took a long time to get other things out of my system and this back into my system," she tells Paula.

Still Unforgettable hits stores Tuesday.

And remember to watch ET Tuesday as Natalie opens up for the first time about her battle with hepatitis.
