Now sometimes there’s collaberations that we didn’t see coming.

But this one might be the best one yet.  Supposedly, Nelly And Taylor Swift really like singing together!

I woulda thought she’d be into singing with someone like Ed Sheeran.

But on Tuesday, she brought him out at a show in St. Louis to sing his new single!

The last time the two sang together was in 2011 when “Just a Dream” was big.

Swift actually sang “Just A Dream” on her own and revealed that she’s actually a really big Nelly Fan!
