Abstract
The bright star γ Psc is among the nearest Population II giants located in the red clump region. Here we demonstrate that γ Psc is actually a core-helium burning horizontal branch star. As such, the τ ≃ 12 Gyr old γ Psc is found to be slightly over-massive at M
HB = 0.97 ± 0.12 M
⊙, which suggests that it is possibly a rejuvenated source.
