Gwen Stefani has revealed that she�s keen to get her second album out by the end of the year.

The pop star has been busy working on new tracks for the long-player and once again will be teaming up with Pharrell Williams on production duties.

She said: "There's a lot of songs that were left over from the last album, and there's some new songs I did with Pharrell.

"There's a lot of Pharrell on this record. I did some stuff with (No Doubt's) Tony (Kanal) and some stuff with Akon."

In the interview with mtv, she described the album as �ear candy.�

Swizz Beatz will also be helping out on production duties. He added: �She's always taking it to the next level. I love her background for music. She likes a lot of Caribbean sounds with hard beats.�
