The former Friends star's series will air on Living at the end of March and she said people shouldn't be put off by the title, which refers to older women who like younger men.
The actress laughed: "I think guys don't like the saying Cougar Town, but once they get past that they're digging it! You can't be embarrassed about the title, you've just got to jump in."
The entire cast came out to meet fans at a special Q and A for the comedy as part of the Paley Centre For Media's PaleyFest 2010 in LA.
But for people in the UK who haven't been able to tune in yet, Courteney explained: "The show is about a woman called Jules, her son and friends, and how she's just starting back in the world [after a divorce] and just trying to figure it out.
"The pilot is a lot of information, it's a fast paced pilot but it slows down and becomes more heartfelt as the show goes. We find our stride and I'd say stick with it because it's amazing, it's really fun."
Over in the States, the show has been recommissioned for a second season.
"It's a huge relief but it doesn't take off the pressure," Courteney said. "If they're going to be so wonderful and have such faith in us then I really want to deliver. So not for my personality does it take the pressure off, for others maybe!"
Speaking on the red carpet, the actress also revealed she was set to make another Scream movie soon. "Yeah I'm doing it, it's going to be fun," she said.
