Demi Lovato insists Ed Sheeran duet will 'definitely' happen
Demi Lovato has promised fans an Ed Sheeran collaboration.
The two acts have previously discussed the possibility of a recorded duet and she told Digital Spy this week that it will take place once they have the time.
She said: "I would love to collaborate with Ed Sheeran. He's here tonight [at the Royal Variety Performance in London]."
"We've wanted to do a song together so it's just a matter of being in the same place at the same time."
