Gwen Stefani is surprised by how successful her fashion line has become.

The stylish No Doubt singer, who first launched her collection L.A.M.B. seven years ago, is thrilled with the pieces in the newest range, which she has spent months creating.

“I never thought it would turn out this good. I’m really spoiled. These jeans are as good as anything I have.”

The 39-year-old star’s new collection focuses on attention to detail and mixes neutral tones with electric shades of purple, red and yellow.

The new line, launched in collaboration with Manhattan International, Inc., will be priced between $48 and $345 and includes a large selection of feminine separates, tailored jackets, skinny jeans, and animal prints.

Gwen admits juggling the label, her singing career, and being a mother to her two young sons, Kingston, three and one-year-old Zuma with husband Gavin Rossdale, is challenging: “I don’t get any sleep.”
