Naya Rivera practiced kissing Demi Lovato

Naya Rivera practiced kissing scenes with Demi Lovato before the cameras rolled on ‘Glee’.

The 26-year-old star plays Santana Lopez – who enjoys a same-sex relationship with 21-year-old Demi’s character, Dani – and they perfected their raunchy scenes by rehearsing off-set beforehand.

She told Access Hollywood:  »I made out with her in my trailer before we shot the scene. So then I just, like, warmed her up. You know what I’m saying. »

Naya has enjoyed spending time working with the teenage idol, who is guest starring as a struggling artist in New York City who befriends Rachel (Lea Michele) and Santana, and was glad to have had her on the hit musical comedy.

Naya added:  »She’s awesome and we’re having a blast and we’re so happy to have her. »

‘Made In the USA’ hitmaker Demi is set to make her ‘Glee’ debut on an episode which airs in the US on October 3 during the second part of the comedy’s two-part extravaganza dedicated to The Beatles.
