Nelly Furtado says working with hubby is 'healthy tension'

Nelly Furtado has revealed that working with her husband Demacio 'Demo' Castellon is challenging, but they share a "healthy tension" between them.

The 'Say it Right' hit maker told People Magazine that working together doesn't always go smoothly when there are differences of opinion, but good things always tend to come out of it, and that's the whole point.

While explaining how their working together doesn't affect their private life, the 35-year-old singer said that they make it work because he's often doing his own thing and she does her own thing, so it's not like they are working together all the time.

Furtado continued saying that Castellon is great in the studio because he challenges her to push her boundaries to make better music.

Furtado has collaborated with Castellon on her worldwide smash hit album Loose in 2006 and 2009's Spanish-language platinum album Mi Plan.
