Alan Thicke's memorial service was a star-studded one that included the likes of Leonardo DiCaprio, Kirk Cameron, and Joanna Kerns in attendance.
But it's clear that all these celebs saw Thicke as a special, rare kind of star.
The stars gathered with Thicke's family members and close friends on the night of Dec. 18 to honor the late actor, who passed away from a heart attack just days earlier while playing hockey with his teen son.
Some spoke at the service, while others came to pay their respects. And many of the A-listers paid personal tributes to Thicke on their own time.
DiCaprio had this to say on Facebook:
Cameron reflected on his "TV dad" on Instagram:
I spent Monday through Friday for seven important years with Alan Thicke as my "TV dad." I'm shocked and truly heartbroken today at the news of his death. Alan was a generous, kind and loving man. I am so blessed to have grown up with him. Chelsea and I send our love and prayers to his family tonight. We will cherish the memories... "sharing the laughter and love."
And Kerns said in an interview with People, "Alan was an unforgettable TV dad and husband. In the course of the show we became dear friends. He was a relentless flirt—handsome, cocky and wickedly funny. But he was also at heart a kind soul with a knack for self-deprecating humor."
Rest in peace, Alan Thicke! You will surely be missed.
