Gwen Stefani introduced her baby, Zuma Rossdale, to the world by posting a really nice picture on her website today. The photo has been taken by her dad Dennis Stefani.

Stefani says, “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.”

The pic shows Gwen touching her baby skin-to-skin and smilingly looking at the camera.

Besides this photo, she was even spotted by some paparazzi yesterday at the Beverly Hills library, accompanying her son. Apparently, an assistant librarian took their photography for the library card.

The No Doubt singer gave birth to her second child back in August. The couple, Gwen and rocker husband Gavin Rossdale, already have a two-year old boy named Kingston.

Just recently, Gavin told PEOPLE how his elder son is getting used to the new member in the family.

“It’s like, here is this guy, and he’s not leaving. [Kingston] is getting used to that. Obviously, there are moments that he’s bugged out that someone is in his spot with his mom.”
