Jim Carrey has reportedly offered to help pay for Cathriona White's body to be flown back to her native Ireland for her funeral.
The 53-year-old actor, who met with his late ex-girlfriend's sister Lisa, mother and stepmother at the home in Sherman Oaks, California where the 30-year-old beautician was found dead on Monday (28.09.15) from an apparent suicide, is "doing everything he can to help" them and is "helping out financially as well."
A source told PEOPLE.com: "Jim is doing everything he can to help. He is devastated, but can't imagine how her family must feel.
"Jim arranged for his driver to pick up Cathriona's family from LAX. Her family has access to his car during this awful visit to L.A. [He's] helping out financially as well."
The on-again, off-again couple first started dating in 2012 after meeting on a film set, but split a few months later.
While they rekindled their romance last May, they recently ended it for the second time, but the 'Kick-Ass 2' star is eager to support her family, whom he has met before.
The insider added: "Jim has spent time with Lisa in the past during her Los Angeles visits. He feels it's his obligation to do whatever he can to help Lisa."
An autopsy to determine the brunette beauty's cause of death is scheduled to take place today (02.10.15), but it is expected to be ruled a suicide as she left several notes, one of which was addressed to the 'Dumb and Dumber to' actor, and pills were located near her remains.
