Jessica was born on February 24, 1994, making her 28 years old. Kelly is also reportedly 27 years old, according to sources. As a result, the sisters are one year apart in age.
It indicates that Matthew is in his early 20s. His actual date of birth is not known, though. Thus, he might have a 2 to 3-year age difference with Kelly and a 5 to 6-year age difference with Jessica.
They all are half-Korean as their mom Kim was born in Seoul before being adopted at age 5.
