Jason Priestley posted an Instagram message to his late friend and 90210 co-star Luke Perry on Wednesday.

Perry passed away from a stroke on March 4th, 2019. He was 52.

With a black and white picture of them together, Priestley wrote, “I don’t even have the words… miss you, my brother. May you Rest In Peace… #riplukeperry.”

Another 90210 castmate, Ian Ziering, paid tribute to Perry. Many of his co-stars on Riverdale did the same.

I don't even have the words... miss you my brother... May you Rest In Peace... #riplukeperry

Hard to believe it's been a year since losing Luke. Though time heals wounds, the pain of loss lasts forever. Miss you so much pal. #RIPLuke
