It's Love, Angel, Music and Baby No. 2 for Gwen Stefani, who gave birth to a boy Thursday. Gavin Rossdale and Gwen Stefani added to their family with the birth of baby Zuma on Thursday. The couple named their son, Zuma Nesta Rock, who weighed 3.77 kilograms.

Zuma Nesta Rock weighed 8 pounds and 5 ounces when he was born Thursday afternoon, according to publicist Dave Tomberlin.

"Mother, baby and family are all happy and healthy," he said in a statement.

The pop star and fashionista has another son, 2-year-old Kingston, with her husband, rocker Gavin Rossdale. Rossdale also has a teenage daughter with fashion designer Pearl Lowe.

Stefani, 38, was propelled to worldwide stardom when the band she was lead singer for, No Doubt, released the album Tragic Kingdom in 1995 which sold 16 million copies.

In 2003 the band broke up, and Stefani launched a solo career. To date she has released two albums. Stefani has racked up numerous hits and best-selling albums over the years, not only as a solo artist but as the frontwoman for the band No Doubt. The 38-year-old has also become a successful designer with her L.A.M.B. and other clothing lines.

She played at Auckland's Vector Arena on her Sweet Escape tour in 2007.

There have recently been reports that No Doubt is back in the studio working on a new album.

Her last album, "The Sweet Escape," was released in 2006, a follow-up to 2004's multiplatinum "Love. Angel. Music. Baby."
