Let $\mathcal M$ be a von Neumann algebra, and let $({\mathcal {L}}_p(\mathcal M),\|\cdot \|_p)$, $1\le p<\infty$ be the Haagerup $L_p$-space on $\mathcal M$. We prove that the differentiability properties of $\|\cdot \|_p$ are precisely the same as those of classical (commutative) $L_p$-spaces. Our main instruments are the theories of multiple operator integrals and singular traces.
