Catherine Zeta-Jones is celebrating her daughter on her 18th birthday.

The Oscar winner, 51, shared a sweet birthday tribute to her daughter, Carys Zeta Douglas, on Tuesday.

"Happy 18th Birthday Carys Zeta! You are everything, and everything is you," the proud mom wrote in the caption. "Thank you for the joy you bring me. At 5 am this morning, you texted me to thank me, for giving birth to you. That's the kind of woman you are. Kind."

"Your wisdom out numbers your years," Zeta-Jones continued. "Your beauty is deep and your heart is big enough to love and envelop the world, your sense of humor......very important.... is insurmountable. I could go on."

The actress cheekily added, "Your Japanese needs some work, but that's doable. I love you angel. Mama."

Last week, the Mask of Zorro star revealed her children with husband Michael Douglas, Carys and son Dylan, 20, could possibly pursue acting in the future.

"The journey I've had as an actor has been extraordinary," Zeta-Jones said during an interview on TODAY. "So I can only encourage them to do what they love."

"They're both extremely bright and they're both studying history and politics," she added before jokingly saying, "And they get all their brains from me."

However, Zeta-Jones admitted that her and Douglas, 76, have suggested other career options to their children because of the pressures of stardom.

"But that said, Michael and I would be the first parents to say, 'You know, maybe you should think of another career,' but we've seen how passionate they are about the craft. They know what celebritydom is. They know the good, the bad, warts and all of that," she said.
