Charice Pempengco's grandmother has revealed that the 21-year-old former Glee star attempted to kill herself.

In an interview on Filipino talk show Showbiz Police, Teresita Relucio said that her granddaughter had cut her wrists because she was experiencing financial problems.

Teresita spoke of how the former Glee star's bank account had been cleared out, even though Charice had previously denied claims she was struggling financially and even paid for a ritzy car in cash.

The singer landed the role as Sunshine Corazon on the hit show after her increasing popularity as a YouTube sensation secured her a segment on Oprah Winfrey's talk show.

The star broke down in tears during an interview with Filipino show The Buzz in June, after addressing rumours about her sexual orientation.

"Yes I am a lesbian," she said. "But to those who can accept me, thank you very much. We are all equal, whether you are gay or straight."

But it looks as though things are looking up for the young star, who posted a happy pic of herself to instagram just yesterday.
