No; it's an adjective, which is used to describe (usually) someone. Although I can't find silliest but have heard people use it, try this: You are the silliest person I've ever met. Person is described by the adjective silliest. Definition of silly: weak-minded or lacking good sense; stupid or foolish

If becoming just a bit more silly, "sillier"; if by far the most silly, "silliest". Sillier would be comparing two objects, silliest, multiple things.
