She had the entire audience singing along.

Urban and his wife, Nicole Kidman, offered a touching memorial statement for Newton-John in the wake of her death.

She was one of the biggest multi-genre stars of her generation.

She's staying positive despite a grim diagnosis.

The actress and singer is auctioning off her famous sexy outfit from the movie to benefit her cancer center.

She's not interested in the statistics.

The Hollywood Walk of Fame features everyone from actors to radio personalities, and there are plenty of Nashville names enshrined there.

No, Newton-John is not dying -- and she's got the Twitter video to prove it.

There are many -- too many -- country stars who have had cancer or have been personally affected by it in some way.
