For a simple complex Lie algebra $\frak{g}$, let $V$ be an irreducible $\frak{g}$-module. Is it true that the weights of the non-zero weight vectors in $V$ are less than the highest weight vector and greater than the lowest weight vector with respect to the partial prderorder on weights? If not, what is a simple counterexample.?

Do weight vectors live between the highest and lowest weights?
