Nelly Furtado may be like a bird, but the star will find it difficult to fly away in her current state: the singer is pregnant.

Star magazine is reporting that Furtado is expecting her second child, this one courtesy of fiancé Demacio Castellon.

She has a four-year-old daughter, Nevis, with ex-boyfriend, DJ Jasper Gahunia.

"She's not very far along yet, so she's trying to keep the pregnancy under wraps," a source close to Nelly Furtado and Demo Castellon said.
