Gwen Stefani is launching a perfume for her L.A.M.B. fashion and accessories line.

Stefani says her deal with Coty Inc., announced Wednesday, is a sign that her success with L.A.M.B. (an acronym for Love Angel Music Baby) is not fleeting.

"It's very prestigious as a designer to have a fragrance. It's a milestone with L.A.M.B., and I don't want L.A.M.B. to go away. The fragrance makes it feel real, like it'll be here for a little while," Stefani told The Associated Press.

"The whole L.A.M.B. thing is pretty greedy. I'm making it all for me," she said. "The goal with this fragrance is that I'll wear it and have endless bottles of it."

Stefani's fragrance, which has not yet been named, will debut next fall. Coty also produces fragrances for Vera Wang, Marc Jacobs, Jennifer Lopez and Sarah Jessica Parker.

"Like Gwen's highly acclaimed L.A.M.B. fashions and accessories, this will be no ordinary perfume," Catherine Walsh, senior vice president, American Fragrances, Coty Prestige, said in a statement.

"From the packaging to the bottle design to the distinctive scent itself, we will be working very closely with Gwen to ensure that her signature fragrance captures her rare spirit, style and warmth."

Financial terms of the agreement were not disclosed.

L.A.M.B. was created and launched in 2003 by Stefani, who had made her own clothes for years.

She teamed with stylist Andrea Lieberman and decided to do her own collection, which has been shown on the runway at New York Fashion Week.

L.A.M.B. also includes handbags, shoes and watches.

Creating a signature scent is more like writing music than designing a dress, the 37-year-old singer told the AP, because there really are not any conventional limits.

She is continuing to tweak the fragrance much like she would a song — playing with the formula until she instinctively feels it is right. An outfit is done when someone tells her she has to leave the house in five minutes, she said with a laugh.

To make the announcement with Coty, Stefani wore a below-the-knee coat dress in a leopard print that she said will be part of an upcoming L.A.M.B. collection, complemented by black pantyhose with seams up the back and high-heel patent leather pumps.

Though she describes herself as a fan of more casual clothes, Stefani said such a dressed-up look has become the norm as she promotes her new album, "The Sweet Escape."

"Each day, it's make a dress, then dispose of a dress and start again the next day. I'm storing them all for later, when I don't do this anymore and I walk into my closet and have all these wonderful outfits."
