Alan Thicke, actor best known for his role as Dr. Jason Seaver on ABC sitcom "Growing Pains," has died at 69.
Thicke had a heart attack while playing hockey with his 19-year-old son, Carter, according to TMZ who was first to report the news.
Thicke starred on "Growing Pains" from 1985-1992, before appearances on "7th Heaven," "How I Met Your Mother," his own reality show "Unusually Thicke" and, most recently, the second season of "Fuller House."
The actor is survived by sons Carter, Brennan and Robin Thicke and wife Tanya Callau, whom he married in 2005.
Tributes from Alan's celebrity friends and fans began pouring in on Twitter after news of his death was confirmed. Paula Patton, ex-wife of Alan's son Robin, seemingly reacted to the news by sharing a quote from Mother Teresa within moments of the news.
