Furtado marries Cuban boyfriend?

Nelly Furtado has reportedly tied the knot with Cuban boyfriend Demacio 'Demo' Castellon.

Music producer Timbaland confirmed that the pair were engaged in July after Furtado was seen with a new diamond ring on her wedding finger.

Singer Natasha Bedingfield congratulated the couple during a gig this week, sparking speculation that they had married.

Furtado has been dating the sound engineer since they collaborated on her 2006 album Loose.

She has a three-year-old daughter with former partner DJ Jasper 'Lil' Jaz' Gahunia.
