She was close to tears during her heartfelt performance at the Stand Up to Cancer Telethon but Taylor Swift couldn't contain her emotions after she left the Shrine Auditorium.

That's when the flood gates opened.

The star broke down in tears as she exited the event on Friday night where she debuted her new song Ronan, which was inspired by a a four-year-old cancer victim who lost his battle to the disease.

Holding on to her mother's hand, Swift was pictured wiping away her tears just moments after her moving performance.
