Ben Affleck admits it's not easy watching Michael Douglas kiss Matt Damon in their upcoming Liberace film, "Behind the Candelabra."

"Pretty jealous, pretty jealous," the "Argo" Oscar winner cracked Tuesday night at the premiere of his new movie, "To the Wonder," when we asked if he was envious of Mr. Douglas.

He added, "It burns me up. You know, I feel the envy in my heart. I can't stand it."

Remember, Damon does refer to Affleck as his "hetero life mate."

"I saw 'Behind the Candelabra,'" Affleck said Tuesday. "I don't know about the hetero part anymore."

"Candelabra," directed by Steven Soderbergh, is the real-life story of Liberace and his very tumultuous relationship his much younger lover Scott Thorson.

"I've seen it," Affleck said. "It's spectacular to see. Matt is amazing. Michael Douglas is amazing. (Steven) Soderbergh's brilliant."

While the film is "light" and "fun," Affleck said, "It's also quite resonate."

We cannot wait.

Also at Tuesday's premiere, sponsored by Disaronno and Fiji Water, were Affleck's costars Rachel McAdams and Olga Kurylenko, Zachary Levi, Katie Aselton, Mark Duplass, Justin Chatwin and Wes Craven.
