Judy Greer said that her best on-screen kiss was with comedy legend Lily Tomlin.

Greer appeared on the "Watch What Happens Live" with host Andy Cohen on Thursday, where a fan asked her which celebrities were her best and worst on-screen kisses, according to People.

Cohen listed some of the major stars Greer kissed throughout her career, including Ashton Kutcher, Gerard Butler, Lily Tomlin, George Clooney, David Duchovny, and Nicholas Cage.

"Lily Tomlin, hello?!" the actress said in response.

The two shared a kiss in the 2015 movie "Grandma," which director Paul Weitz wrote with Tomlin in mind for the main role, the Chicago Tribune reported at the time. The film also featured Julia Garner, Marcia Gay Harden, Laverne Cox, and Sam Elliott. Greer played Tomlin's ex-girlfriend in the film, according to InStyle. Tomlin earned a Golden Globe nomination for best actress in a comedy or musical for her performance in the film.

"I kissed her in a movie that I love, called 'Grandma,' and I have to say she has very soft lips," Greer continued.

Representatives for Greer and Tomlin did not immediately respond to Insider's request for comment.

Greer is currently promoting her new show, "The Thing About Pam," which is based on a murder case from 2011. Greer stars alongside Renée Zellweger, Katy Mixon, and Josh Duhamel.

The NBC limited series has six episodes and began airing on March 8, but is available to stream on Peacock and Hulu.
