In the here-now, gone-in-a-flash world of celebrity fashion lines, there’s one surprise survivor who might be on her way to becoming a $1 billion fashion powerhouse: The Jessica Simpson Collection.

Fragrance, shoes, clothing and accessories make The Jessica Simpson Collection very very popular and earned the singer/style icon $750 million dollars this year.
The projections hit $1 billion dollars for next year as she expands her line to include sportswear that comes out in late 2011.

“She is the girl next door and has great product,” says [Licensing CEO Vince] Camuto, adding, ”People like her. People look at her as a style icon.”

Simpson has a lot to be happy about. Her empire is making her loads of money and she just got engaged to former NFL player Eric Johnson.
