The closest Wolf-Rayet star, WR 11 in the binary system 2 Velorum, is the only star for
which the spectral signature of the ^{26}Al produced in its core is expected to be detectable with current gamma-ray instruments, through the 1.8 MeV decay of that radioactive nucleus.

We present here the current status of both model predictions, from calculations of massive star evolution including rotation of stellar interior, and from data on 2 Velorum obtained by the ESA's gamma-ray satellite INTEGRAL over the first year of its mission.
