Kareem Abdul-Jabbar celebrated Bruce Lee's 80th birthday online

Basketball Legend Kareem Abdul-Jabbar celebrated martial art legend Bruce Lee's 80th birthday on Friday.

The NBA legend, actor and best-selling author conducted a conversation with the martial arts icon's daughter, Shannon Lee, in honor of what would've been Lee's 80th birthday, reports The Hollywood Reporter.

Abdul-Jabbar and Lee were close friends who appeared on screen together in the classic "Game of Death."

Bruce Lee died in 1973 at the age of 32.

Abdul-Jabbar, and the Lee family, made headlines last year when they blasted Quentin Tarantino for his depiction of the legend in Once Upon a Time... in Hollywood.

On Instagram, Abdul-Jabbar referred to Lee as a "mentor," while promoting the sale of inspirational T-shirts and masks with an image of both men accompanied by the message: "Make a friend that doesn't look like you … you might change the world."

"We had an unlikely friendship — a 7-foot-2 basketball player and a 5-foot-8 martial artist — but we had a shared interest in music, the arts, philosophy, and improving the lives of people who looked like us," Abdul-Jabbar said about the apparel collection sold through his Iconomy management enterprise.

"We believe that tackling systemic racism starts with making a friend who doesn't look like you and creating empathy for others. That's what we're hoping to promote with our social justice champion/social justice warrior efforts."
