Jim Carrey's legal team has won its bid to have his ex-girlfriend's medical records granted admissible in court, meaning that he will use them to defend himself in the wrongful death lawsuit against him.

His girlfriend, Cathriona White, 30, an Irish make-up artist, died in September 2015 from a fatal overdose of prescription drugs.

Lawyers for her estranged husband Mark Burton and mother Brigid Sweetmen claim the actor, 55, used his "wealth, influence and celebrity status" to provide the medication.

But Raymond Boucher, for Carrey, argued that White had recently had breast augmentation and had been prescribed medication that could have been responsible for her death.
