Nelly Furtado allegedly pregnant

Nelly Furtado is reportedly pregnant with her second child.

The Maneater singer is said to be thrilled after learning she is expecting a baby with her sound engineer fiancé Demacio Castellon, but is trying to keep it a secret.

A source close to the singer told America’s Star magazine: “She’s not very far along yet, so she’s trying to keep the pregnancy under wraps.”

However, a representative for Nelly – who already has a four-year-old daughter with ex-partner DJ Jasper Gahunia – insisted: “She is not pregnant.”

Nelly recently revealed she once turned down a $500,000 offer to pose nude in Playboy.

The star admitted she was flattered when Playboy’s boss Hugh Hefner asked her, but decided to keep her clothes on so her future lovers would have something to look forward to.

She said: “It was tempting. It almost plays on your vanity. But I like to save a little bit for the bedroom. It’s something to be preserved, a little bit for yourself. But that’s not to say that I would never do it. As a pop star, people would love to see you naked every day.”
