Stylist to the underfed stars, Rachel Zoe, was on Tyra on Friday to promote her new book Style A to Zoe: The Art of Fashion, Beauty, & Everything Glamour. Team Chunk spokeswoman Tyra asked Rachel about the rumors that she supplied her skinny clients — like Lindsay Lohan and Nicole Richie — with diet pills from Mexico (a tidbit that was on Rachel’s Wikipedia entry for a long time up until her book’s release). Of course Rachel denied the diet pill thing, and of course Tyra let her off the hook immediately. Way to stick up for the thick girls there, TyTy! Anyway, we’re pretty sure Rachel got some Botox (finally! she was bound to lose an accessory in those frown lines, they were so deep), and she’s unable to move her forehead. Take a look after the jump.
