The former Oasis star, who launched the line in 2009, has reportedly hired investment bank Cantor Fitzgerald to help assess his options in raising funds to increase the men's fashion label's presence.

Gallagher currently has 15 Pretty Green stores in England and Scotland, and editors at British newspaper The Independent report he now plans to take the venture overseas.

The hitmaker's stake in the business is reportedly worth $9.6 million (£6 million) while other investors include U.K. soccer star Joe Cole.
