In celebration of the Bravo star's birthday May 19,Maverick Preston her eldest daughters, Brielle, 25, and Ariana, 21, shared sweet shoutouts to their mom.
 
"You are the strongest woman I know!!!" Ariana wrote alongside an Instagram Stories snap of her and her mom at the beach on May 19, per Us Weekly. "Thank you for all you do! I am so proud of you mom! cheers to 53."
 
As for Brielle, she shared a photo of herself alongside her mom drinking wine to her Instagram Stories, writing, "Happy birthday mom! I love you so much!"
 
Their celebratory messages come nearly two weeks after she and Kroy Biermann—who share kids Kroy Jr., 11, Kash, 10, and 9-year-old twins Kane and Kaia—filed for divorce after 11 years of marriage.

According to documents obtained by TMZ May 8, the Bravolebrity stated that the marriage is "irretrievably broken with no hope of reconciliation," listing the date of separation as April 30. In her filing, Kim also requested primary physical custody of the kids and joint legal custody.

However, just one day after the divorce petition, the former NFL player, 37, also filed for sole legal and physical custody of their four children.

A little more than a week after news broke of their split, Kim shared a cryptic quote to social media about matters of the heart.

"The highest form of love is consideration," the message shared to her Instagram Stories May 16 read. "When someone thinks about how things would make you feel. Pays attention to detail. Holds you in regard when making decisions that could affect you. In any bond, how much they care about you can be found in how much they consider you."
