Robbie and Emma sound damn good as a duet.
The pair performed Spice Girls hit 2 Become 1 (it was Christmas number 1 in the UK exactly 20 years ago) in front of some lucky listeners, in a gorgeous stripped-down cover.
They were performing at a Live Heart gig in a secret London venue with only 300 attendees.
The Spice Girls reunion seems to be a bit all over the place at the moment, but moments like this are definitely tiding us over for the time being. Robbie meanwhile, as we know, has been doing fab since going solo from boy band Take That.
