Feel old yet? TLC's Rozonda "Chilli" Thomas is a first-time grandma.

The 53-year-old singer's son Tron Austin announced the birth of his baby girl on Saturday along with photos of him with wife Jeong Ah Wang posing together at a hospital in South Korea.

Their daughter was born ahead of her due date on March 6, Austin revealed, adding that his newborn's name is Lua.

Wang had "an emergancy C section," her husband wrote in the caption. "Our nerves were high and our anxiety was through the roof but despite all of that she powered through and gave birth to a healthy beautiful baby girl!! I am so beyond proud of her bravery and courage to do this so off guard."

"Eternally grateful to say we have officially started our family!" Austin added, calling it a "dream come true" since the couple began dating in September 2018. "Life's journey has now truly begun!!!"

Chilli has yet to publicly comment on her newly-minted status as a grandmother.

Austin, who Chilli shares with songwriter and producer Dallas Austin, previously shared his desire to become a father in an interview with People in April where he discussed the impact his mom's sacrifices while touring with TLC had on his view of parenthood.

"It's a very hard job and you can't be there all the time, even when you have kids, you have to keep going in this direction. As an aspiring father, I think of how I want to do similar with my kids," the "Family Legacy" star said.

He added: "I want to make sure I'm there as much as possible, but that they also understand that daddy needs to do what daddy needs to do, and it doesn't change the love between us."

Austin and Wang later announced her pregnancy on Instagram in September, revealing his wife's difficult fertility journey and miscarriage.

"I am in awe of your efforts and I am blessed and honored by Jesus himself to begin this journey with you," he wrote in the caption. "I love you so much you are going to be the best mother EVER ! We came a long way 5 years later we are married and expecting our first child. loyalty goes a long way."

Austin's mom commented, "A blessing indeed."
