"Someone who was always there for me, someone who always had the right answer, no matter how silly, or serious the question, someone who always stood up for what he believed in!" the 33-year-old star continued. "Someone that helped everyone he came across, someone that cared about people that didn't care about him! Someone that truly loved life! And believed in God with all his heart!"
Bear, who shares River with Raiven Adams, concluded, "I have large boots to fill! And I will give my all to try to fill them!!!! Happy 1st Birthday River!!!! Daddy loves you!!!"
Last month, Bear similarly paid tribute to his dad with an Instagram post, sharing that he's "glad" Billy got to meet River before his death.
"I'm glad my Dad got to meet my son, his grandson," he captioned two photos of Billy with River. "I will always remember the twinkle in his eyes when he held him! Hold tight to your loved ones! You never know when it's the last moment you'll get with them."
