Oh, to be the daughter of reality royalty. Kim Zolciak’s daughter, Ariana, turned 11 earlier this week and the very pregnant Real Housewives of Atlanta star pulled out all the stops for the adorable girl.

Kim took to her fave social media platform yesterday morning to express her excitement, tweeting, “Happy 11th Birthday to my beautiful daughter @arianazolciak Today is going to be amazing  I love you soooo much! #soproudofyou.”

The proud mama, who is expecting twins with NFL hubby Kroy Biermann, gave a Twitter update by way of a video later as well.

“Celebrating @arianabiermann birthday tonight with her friends! She HAD to have a Publix cake and it's says ‘Happy Birthday Ariana BIEBER’,” Kim tweeted along with the video.

The new 11-year-old isn’t just a huge fan of the Biebs. She apparently also loves 9-year-old rapper, Matty B, and she even wrote to him on her birthday, saying, “can you plz follow today’s my birthday,” adding later that she is “his biggest fan.”

Little did she know she was in for the surprise of her life, as her celeb-mom had arranged for Matty to come to her birthday party.

Ariana tweeted, “Omg!! Thank you so much mattyb for coming to my birthday you are so sweet!! You are the best birthday present ever!! @MattyBRaps.”

Not wanting to leave anyone out of the action, Kim later posted an Instagram picture of lil’ Kash eating some birthday pizza while sitting outside. She lamented the lack of flash, but his cuteness overrides the mistake.  

Seriously does this family do anything without announcing it on social media? Regardless, we’re glad to get the scoop, and only wish we were invited!
