Jim Carrey's ex-girlfriend Cathriona White, 28, found dead from an apparent suicide just days after breaking up with the comedian for a second time

Jim Carrey's ex-girlfriend Cathriona White, 28, has committed suicide, law enforcement sources tell TMZ.

The Irish make-up artist was found dead at her Los Angeles, California home Monday night, after two friends showed up at the residence to check in on her.

News of her death comes just five days after breaking up with the comedian for a second time.

TMZ reports, according to sources, that White left a suicide note in which she said she broke up with Carrey on September 24. That was the same day that she wrote a worrying message on Twitter.

'Signing off Twitter, I hope I have been a light to my nearest and dearest,' White wrote.

It's believed that White died from a drug overdose.

The couple first met in late 2012 but by March the following year it was all over.

While Carrey never said why, the comedian did confirm that he had split from the former makeup artist to the Irish Independent.

He said in March 2013: 'I did go out with an Irish girl. We're not seeing each other anymore. But she is lovely.'

However, by May of this year, the couple had rekindled their romance and were seen happily holding hands on outings in New York.

Jim has twice been married. In 1987 he wed Comedy Store waitress Melissa Womer; they stayed together for eight years and have a daughter, Jane Erin Carrey, who was the same age as White and has a child of her own.

A year after Carrey's split from Womer in 1995, the actor married his Dumb and Dumber co-star Lauren Holly, but that marriage lasted less than a year.

After than he was involved in a number of relationships with other actresses including January Jones, Laurie Holden and Me Myself and Irene co-star Renee Zellweger, to whom he was briefly engaged.

In 2005 he began a five-year relationship with Jenny McCarthy, and became a step-father to her son Evan.
