Freddie Prinze Jr broke down in tears on Hollywood's famed Walk of Fame when he paid tribute to his late father, who was being honoured with a star.

Fans initially thought the actor was upset because his wife SARAH MICHELLE GELLAR was unable to attend the event, but his speech revealed there was more on his mind.

In paying tribute to his father, the SCOOBY-DOO star sobbed, "This is for my family, my mother who has tirelessly loved him and my grandmother MIRIAM in Puerto Rico, who couldn't be here, who has honoured his name more than I could ever dream to.

"I love them both, love my family. I'm glad this could happen... I thank you from the bottom of my heart."
