Brielle Biermann Was Gifted a Rose Gold Gun for Her 21st Birthday

For Brielle Biermann's big 21st birthday, her parents, Kim Zolciak-Biermann and Kroy Biermann, knew exactly what to gift their daughter with on her big day. Kim presented her eldest daughter with a rose gold gun, according to Brielle's Snapchat, via Us Weekly.

In a video posted online, Brielle asked her mom what she should do with the unexpected birthday gift and offered up this answer: "You're moving out so it's time you figure it out ... It's a very special one for you. It's rose gold." According to Us Weekly, Brielle also thanked her dad on social media: "Rose gold gun!!! Thanks papa.” 

Brielle's mama also used the big day to pay homage to her not-so-little girl. "Dedicating today to my beauty @briellebiermann the very person that gave me strength to keep pushing!! I had Brielle at almost 19, I was so excited I could barely stand it but I was a nervous wreck at the same time! My side kick, My heart, My strength, My pride and joy, My best friend, My daughter YOU amaze me!! We made it Elle I always knew we would," the Don't Be Tardy matriarch wrote on Instagram. "You are such a blessing to this world! Thank you for making my 'job' as your mom an easy one! I truly mean that from the core of my being! I made it through the night last night barely, no sleep worrying about you .. I guess some things will never change no matter how old you get!"

In addition to the gun, Kim also presented her daughter with a topless bust, which matches one she previously gave to her, TMZ reports.
