On a 2018 episode of "The Real," Tamera shared that Tia was actually playing Camryn during the birthday-party scene.
The actress was doing the Lifetime show "Strong Medicine" at the time, and there was a scheduling conflict, so the production staff asked Tia if she could play Tamera's character for two days of filming.
"And Tia was like, 'Sure, why not? You know, that's my twin, I can do it,'" Tamera said.
The hair and makeup teams drew a fake mole on Tia's face, changed her hair, and made it work.
