Kirstie Alley Says She Is A Size 6?

Extra interviewed Kirstie Alley on the set of Dancing With The Stars where the actress revealed she's a size 6?  Wait a minute is she talking about her shoe size?  I'm not her to make fun of delicious candy coated cubbies, but she knows we can see her right?  Is she taking a marker and drawing a 6 on her pants or something?
