Lindsay Lohan stopped by the Letterman show last night to plug her latest masterwork of modern cinema, Herbie: Fully Loaded, and to do the kind of light image rehabilitation that must accompany any of her public appearances. There was a time when The Breast Question was the one she needed a quick answer for (if memory serves, it was "I blossomed!"); now it appears that Lohan's publicists have retrofitted the old breast party line for The Weight Question (which, naturally, is the polite, thinly veiled version of The Drugs Question), as she told Letterman she owes her new stick-figure to "puberty," that wonderful transition to womanhood that Lohan claimed only to have undergone at the age of 17. This makes perfect sense, for when we think of Lindsay Lohan, the phrase "late bloomer" is always prominent in our mind.

Gawker details Lohan's other talking points from a Today Show appearance (Letterman didn't give her the opportunity to rattle off the list), but rest assured, puberty was discussed, and we grow ever sadder that her dad's not around to have that uncomfortable father-daughter talk about the exciting changes that are happening to her body.

Oh, and while we're in the neighborhood, Lohan's uncle was arrested for alleged mail fraud involving 9/11 relief money. So it goes.
