Last year on The Real Housewives of Atlanta, we totally wiped away tears after Kim Zolciak’s daughters, Brielle and Ariana, lovingly toasted their mom and her then-boyfriend Kroy Biermann at a baby shower before KJ was born, and now Brielle has moved us yet again with her kind words.

In honor of “dad” Kroy’s birthday — Kroy is not the biological father of either of Kim’s daughters, though he has said he plans to legally adopt them — on Sept. 12, Brielle wrote a sweet message for the 27-year-old footballer on her Instagram page, alongside a picture of Kroy’s decadent birthday cake. Below is Brielle’s sweet note to Kroy in its entirety.

“Happy birthday kroy! I'm so thankful for you. I don't have my father in my life, and even though you weren't there for 13 years of my life- you are now and make up for all the years you haven't been there. u make me feel like my actual dad. I'm so blessed to have you and so luck you're in our lives. you came at the perfect time. everything happens for a reason. we have our ups and downs and our fights but were supposed to! you're my dad! but at the end of the day, you're always there for me. you're always here for me and the shoulder I can cry on. I love you daddy, and can't wait for all the other fun moments we'll have!!! I hope you had a good birthday- I love you.”
