Gina, I mean Tisha Campbell, said a lot without saying anything. Her body language says it all! She was asked about a "Martin" reboot when she suddenly got really shy but also said, "It's very exciting."
It doesn't help that Martin's fiancee posted the below picture on Instagram...
And then there's a photo of Tisha Campbell with Martin costar, Tischina Arnold who played Pam in the show. Are these hints???
