The singer ended the message by saying she was “about to go have the best day ever.”

She truly is an icon, one of the all-time great pop stars & I love her dearly.

I hope you all love it!"

“Hold Me Closer” pays tribute to some of the legend’s earlier gems.

Is Brit’s comeback as fresh and inspired as we’d hoped?

On Thursday, Spears left Instagram and took to Twitter to share her feelings about the duet.

“Okie dokie … my first song in 6 years!!!!

“I’m kinda overwhelmed… it’s a big deal to me!!!”

Both singers teased their duet before its release.

“Thanks @eltonjohn for posting my baby pic!!!

Most people say that it’s CUTE … it surely is!!

!,” she wrote, perBillboard.

How cool is it to be a background voice ON YOUR song!!!

Sir Elton, I did it thanks to your genius, creative, and legendary mind!!!

I am so grateful!!!

I just keep on giving, don’t I???

Can I get an AWWWWE???”

“Can’t wait for everyone to hear what we’ve been working on!”

The wait is over.
