Another photo showed him planting a kiss on her forehead on set, while a third depicted the entire Friends cast sharing a hug behind the scenes of the award-winning sitcom.
“One year,” Jen wrote in the caption, alongside a dove emoji and a heart wrapped in a bandage.
Courteney – who played Matthew’s on-screen wife Monica Geller in the hit show – also shared a series of candid images on her own Instagram, writing that she missed her late friend “today and always”.
Matthew was found dead at his home in Los Angeles in October 2023, at the age of 54.
“The best thing about me, bar none, is if someone comes up to me and says, ‘I can’t stop drinking, can you help me?’ I can say, ‘yes,’ and follow up and do it. That’s the best thing,” Matthew claimed in 2022.
“And I’ve said this for a long time — when I die, I don’t want Friends to be the first thing that’s mentioned. I want that to be the first thing that’s mentioned, and I’m going to live the rest of my life proving that.”
