Depending on your age, you know this Barbie character as either Kelly or Chelsea; Mattel changed her name to the latter in 2011, partially because Europeans called her Shelly and they wanted a universal name. Nowadays, Chelsea is the youngest of Barbie’s siblings. She was introduced in 1995 and was renamed in 2011.
The doll was originally more of a toddler before Mattel began to slowly age her up as well. The most common Chelsea iteration is about 7 years old. Earlier in 2023, Mattel launched a series of disabled Kelly dolls, including one with scoliosis. “We’re proud to launch the first-ever Chelsea doll to continue to be more reflective of the world kids see around them,” Lisa McKnight, executive vice president and global head of Barbie and dolls, said in a press release at the time, per Hype Bae.
Chelsea (and Kelly) do not appear in “Barbie.”
