How old are Will children?

As of my last knowledge update in September 2021, Will Smith has three children: Trey Smith, Jaden Smith, and Willow Smith. Their ages at that time were as follows:

- Trey Smith: born on November 11, 1992, he was 28 years old.

- Jaden Smith: born on July 8, 1998, he was 23 years old.

- Willow Smith: born on October 31, 2000, she was 21 years old.

Please note that these ages may have changed since then, so it's best to refer to a more up-to-date source for the most recent information.
