Nelly has decided to try something different for her third single to be released from the album, Loose.
A gentle guitar, slow beats and even some whistling all come together to make a song which shows off Nelly's voice.
Get a box of tissues ready as Nelly is feeling a little bit sad.
She sings about things being great but then going wrong. "Why do all good things come to an end?" she asks.
Will you still be humming it next week?
THREE NELLY FACTS
It's Nelly's birthday on 2 December

Nelly can speak English, Portuguese, Spanish and Hindi
The song doesn't have the energy of Nelly's other singles from this year but it is nice to hear something new.
Will it make the charts?
She has already scored eight Top 40 hits, and having found more fans with her new dance sound, this should be Nelly's ninth.

I love Nelly but this song didn't catch my heart, so it won't be on my playlist! Better luck next time Nelly!

Love it! This is sooo like the old Nelly that there is no way her old fans wouldn't love this beautiful song! Her voice is amazing and the video is fantastic!
