Teen pop sensation Britney Spears — who was just named the worst-dressed celeb by Mr. Blackwell (see below) — will make her feature film debut in a coming-of-age story described as Boys on the Side meets Duets. According to The Hollywood Reporter, the "Untitled Britney Spears Project" will go before cameras in March and will be co-financed by Spears's record label, Jive Records.
