Pregnant pop star BRITNEY SPEARS is desperate to go into business with WALL STREET star CHARLIE SHEEN after falling in love with his range of kid's clothing. Sheen launched his hugely successful Sheen Kidz line in April (06) with business partner MICHAEL BERENS and the range is now sold in more than 125 stores. A source tells US OK! magazine, "Brit's people approached Sheen Kidz out of the blue. She'd seen his clothing and really liked it. "She wants to start her own children's clothing line and she thought Sheen Kidz would be able to help get things off the ground." The TWO AND A HALF MEN star is reportedly open to expanding his business with the pop star. The source adds, "Charlie believes it would be fun to work with Britney." The TOXIC singer, whose son SEAN PRESTON will celebrate his first birthday 14 September (06), is due to deliver her second around the same time.
