Precise radial velocities from the Anglo-Australian Telescope (AAT) confirm the presence of a rare short-period planet around the K0 giant HD 121056. An independent two-planet solution using the AAT data shows that the inner planet has P = 89.1±0.1 days, and m sin i = 1.35±0.17 M_Jup. These data also confirm the planetary nature of the outer companion, with m sin i = 3.9±0.6 M_Jup and a = 2.96±0.16 AU. HD 121056 is the most-evolved star to host a confirmed multiple-planet system, and is a valuable example of a giant star hosting both a short-period and a long-period planet.
