Don't be tardy … for the vow renewal. Kim Zolciak is celebrating her five-year marriage to Kroy Biermann with a recommitment ceremony.

Wearing a white gown and joined by the couple's six kids, Kim looked stunning as she posed alongside her beautiful family on the beach.

"I am the LUCKIEST wife/mother on this planet! I never will ever take my family for granted! God is so good," she captioned a photo of the gang on Instagram.

Her daughters, Brielle, 20, Ariana, 15, and Kaia, 3, also wore matching white dresses for the occasion, while the boys Kroy Jr., 5, Kash, 4, and Kane, 3, opted for khaki shorts, suspenders, and pink bow ties.

However, the family friendly event turned slight NSFW when Kim, 38, lowered her strapless ballgown and went completely topless for a few shots — much to husband Kroy's approval.

"My wife," the former NFL star wrote alongside the Bravo beauty's racy photo, which definitely did not surprise fans.

The couple, who tied the knot in 2011, revealed earlier this year that they were planning to renew their vows while on vacation in Italy.

"I asked Kroy to, I guess, renew our vows. I don’t know if I asked you or I told him or something,” Kim told The Daily Dish, when Kroy, 31, chimed in, “She told me she had planned this whole big thing to renew our vows.”

The timing could not be better for the pair after it was revealed Kim was rejoining the cast of RHOA amid her feud with Kenya Moore, who claimed the couple was having financial troubles.

"Hmm, this s–t is funny!!" Kim wrote. "6 seasons in on Don't Be Tardy, multi-million dollar skincare line in less than 6 months @kashmerekollections meanwhile you sell your hair care products out of the trunk of your car and paying Sally's beauty supply to do an appearances there AND you are spending what you do have on your 3rd paid boyfriend."

She continued, "Sweetie don't try and come for me so you can have a story line for next season. Thx to all my supportive followers for keepin me in the loop!"
