Stefani planning second album

Gwen Stefani has revealed she plans to release a second solo album before the end of the year.

She says she plans to work with the Neptunes' producer Pharrell Williams on tracks that didn't make her debut album Love Angel Music Baby, as well as writing new songs. Pharrell produced her new single Hollaback Girl, due out on May 23.

Among the leftover songs that may be considered for the second album are two songs written with Linda Perry: Fine By You and Wonderful Life For Him, the second of which features Depeche Mode's Martin Gore on guitar.

The singer said: "It's really hard to choose, just because I want everyone to hear all the songs."
