New York - US singer Gwen Stefani released the first official photo of her second son, Zuma Nesta Rock Rossdale, on her website two months after his birth.

"Gwen, Gavin, Kingston and Zuma are all doing well and enjoying being a party of four," the message posted Wednesday said, referring to Stefani's husband, fellow singer Gavin Rossdale, and their first son, 2.

The photo shows a bare-shouldered Stefani, 39, holding Zuma against her shoulder and was released after numerous paparazzi photos of the newborn have appeared recently. The photo, which can be published for free, would drastically sink the value of the paparazzi shots, the New York Daily News said.

The English actress Minnie Driver also posted a picture of her newborn son, Henry, who was born in September, on her MySpace page to discourage curious paparazzi.

Nicole Kidman and Halle Berry had also refused to sell photos of their first children, deals that are highly lucrative for entertainment stars. (dpa)
