During his heartfelt tribute on social media, the 47-year-old singer and actor shared a handful of throwback photos of him spending quality time with his and Whitney Houston's baby girl over the years.
Taking to Twitter, Brown shared the series of photos along with the all-caps caption, "TODAY WE CELEBRATE YOU BABY GIRL."
Bobbi Kristina was 22 when she passed away in July 2015, nearly six months after she was found unresponsive in a bathtub.
Earlier this year, the heartbroken father was photographed sporting a bomber jacket featuring a photo of his daughter on the back, adorned by the words, "My Angel in Heaven."
"Krissy was and is an angel," Brown previously shared when speaking out on her tragic passing last year. "I am completely numb at this time. My family must find a way to live with her in spirit and honor her memory. Our loss is unimaginable."
Take a look at how Bobby Brown is honoring Bobbi Kristina today for her birthday in the posts below.
