Pop superstar Sarah Geronimo explained on Sunday the medical reason that led to the sudden postponement of her joint concert with Bamboo, which was originally scheduled on October 1.

Concert producer Viva Live, in its September 28 announcement of the postponement, did not specify the "unexpected medical condition" that prevented Geronimo from performing, prompting speculation.
