Demi Lovato and Naya Rivera will soon be locking lips on “Glee,” but it turns out the two actresses got in a little practice before shooting their big scene.

“I made out with her like in my trailer before we shot the scene. So then I just like warmed her up. You know what I’m saying?” Rivera tells Access Hollywood in a new interview. “She’s awesome and we’re having a blast and we’re so happy to have her.”

Also a topic of discussion was the show’s upcoming Cory Monteith tribute episode. Rivera discusses how she found out about the news, and why she thinks the tribute episode was the best way to honor the late actor.

“I think that we’re doing a really good job on the episode, and I think that it’s really important to do because there are so many fans that love him just as much as we do, but it’s still tough,” she says.

Rivera was on the talk show to discuss her new single “Sorry,” which features her boyfriend Big Sean. She says the pair met and fell in love after she followed him on Twitter, and admits she would be totally happy marrying and starting a family with him.

“Glee” returns to FOX at 9 p.m. on Sept. 26.
