Jenner, 24, and Scott, 30, are parents to 3-year-old daughter, Stormi, who was born in February 2018. The pair kept Jenner's pregnancy a secret at the time.
Jenner and Scott have been dating on and off again with the couple announcing a split in October 2019 after two years together.
The Kylie Cosmetics founder previously said in February 2020 that she had a "great relationship" with Scott.
"We're like best friends. We both love Stormi and want what's best for her. We stay connected and coordinated," Jenner said at the time.
