A popular Philippine senator and daughter of one of the country's most famous movie couples has announced she will run in next year's presidential election.

Grace Poe declared her candidacy Wednesday at the University of the Philippines, joining two other politicians who have made public their presidential ambitions. They are former Interior Secretary Mar Roxas and current Vice President Jejomar Binay.

Poe lived for years in the United States, and questions have been raised about her citizenship and length of residency in the Philippines.

She is the adopted daughter of Susan Roces and the late Fernando Poe Jr., who were immensely popular in the local movie industry.

Current President Benigno Aquino III's six-year term ends next June.
