Mary Kate and Ashley Olsen seem to have little time for corporate boredom and a large appetite for early death at least according to sources at their production company Dualstar Entertainment Group.

TMZ has learned that the 20-year-old media titans and some-time NYU students, come into Dualstar’s Culver City, Calif. offices around every 30 days.

But instead of attending executive meetings or going over financial reports, the doll-like duo prefer to hole themselves up in an office and chain smoke cigarettes for hours at a time.

Besides being an appetite supressant and bad for you, according to California law smoking indoors in public places also happens to be illegal.

Child stars will be child stars, but I might be persuaded to build a large gold statute if there is ever a child star that can grow up without self destructing and the ill-effects of going through puberty in Hollywood.
