Courteney Cox has paid tribute to her Friends co-star Matthew Perry on the one-year anniversary of his death.
Perry, who played Chandler Bing in the hit US sitcom, died on 28 October last year at the age of 54 from the "acute effects of ketamine".
One of two doctors among the five people charged in connection with Perry's death pleaded guilty earlier this month to illegally distributing ketamine.
Cox, who played Perry's on-screen wife Monica Geller, remembered the late TV and film star in an Instagram post captioned: "Missing you today and always."

The Scream star shared a photo of her with Perry and another of them with the rest of the Friends cast - Matt LeBlanc, David Schwimmer, Jennifer Aniston, and Lisa Kudrow.
Aniston also shared a selection of photos of Perry to her Instagram account on Monday and tagged the Matthew Perry Foundation, which was set up in the wake of the star's death to help those struggling with addiction.

During his life, Perry was open about his battle with substance abuse and addiction. He set up a sober-living facility for men with similar issues.
Following his death, the Friends cast said in a joint statement to the US publication People that they were "utterly devastated".
Perry had been seeking treatment for depression and anxiety when he became addicted to intravenous ketamine.
Ketamine is a sedative that can be used as a recreational drug, as well as to treat depression and pain management.
Perry's mother, Suzanne Morrison, recently said he appeared to have a "premonition" about his death on one of the last times they spoke.
In an interview with NBC's morning talk show Today to mark the anniversary of Perry's death, Suzanne Morrison said: "He came up to me and he said, 'I love you so much and I'm so happy to be with you now'.
"It was almost as though it was a premonition or something. I didn't think about it at the time, but I thought, 'How long has it been since we've had a conversation like that? It's been years'."
