The 18-year-old singer and YouTube star, who came out as pansexual in January (21), is planning an early feast with her parents and older brother Jayden.
"(My family and I) are going to celebrate Thanksgiving early because my brother is going to be out of town for Thanksgiving, and we want all of the family (together)," she said during a video call with members of the "It Gets Better" project and Facebook's Pansexual Pride group.
The "Boomerang" hitmaker is also celebrating her first Friendsgiving, an alternative get-together with pals instead of family members.
"I feel like Friendsgiving is such a (great) time that you get to celebrate with your chosen family, which is something that I think is really, really, really important," JoJo said of getting together with Jenna and Luke Eisner, the vocal coach on "Dance Pop Revolution".
"You get to just laugh and sit around and have fun and give each other love and support."
Meanwhile, the Siwas are so gung-ho about the holiday, they celebrate it again in April.
"We do Thanksgiving twice a year," she laughed. "We do Thanksgiving in November and we do Thanksgiving in April because we miss it."
And she also gushed about the delicious food her mom, Jessalynn, makes for the feast day.
"My mom's gravy... it will change your life," she gushed. "There's corn, potato casserole, and green bean casserole, turkey, and ham."
