Lovely Scottish songstress Nina Nesbitt was sweet enough to pop over to our fabulous heat area at Virgin Media's V festival to talk to us about Niall Horan.br The Don't Stop star told heat's big boss Lucie Cave how her and One Direction's Niall - who's also at this weekend's festival - bond over their mutual Celticness.br Hmmmm, we're not sure if Celticness is even a word, but we're going with it...
