New York, Oct 31: Singer Gwen Stefani has introduced her 3-month-old son Zuma to the world by posting her photo on her website.

The photo shows seemingly naked Stefani holding her son with a caption "We wanted to share with you the first photo of Zuma Nesta Rock Rossdale. Gwen, Gavin, Kingston and Zuma are all doing well and enjoying being a party of four," reports the New York Daily News.

The photo came after paparazzi photos of the tiny tot began to surface.

Meanwhile, the 39-year-old star, who delivered her second baby Zuma Nesta Rock in August, has apparently been suffering from post-pregnancy weight woes that make her “feel like a giant house”.

The singer, who shot to fame with rock band ‘No Doubt’, is said to be going ballistic over shedding her extra fat, and has even hired a personal trainer to help her. (ANI)
