Watch as Jessie J was joined by surprise guest Nathan Sykes for his first solo performance alongside DJ Cassidy to deafening fangirl screams in this #STB video

When Jessie J said she was bringing out some special guests on stage, no-one expected it to be the first solo appearance for Nathan Sykes - and the screams that followed showed she had made a fantastic choice! #fangirlingallovertheplace

Nathan and Jessie were also joined by DJ Cassidy for 'Calling All Hearts' at Wembley Stadium - that is definitely a #CapitalSTB dream team! Jessie was 'Calling All Hearts, to the dance floor' and it worked - the #heartbeats were out in force to support their hero. 

If you want to see the stadium erupt at the sight of Nathan once again, you can relive the moment with our video above. *SCREAM*
