(CBS) During a press conference in Moscow to promote the R-rated comedy "Friends with Benefits," Mila Kunis encountered one Russian reporter who had a pointed question for her co-star, "SexyBack" singer-turned-actor Justin Timberlake, which seemed to infuriate Kunis.

When asked in Russian why Timberlake was acting instead of making more music, Kunis took offense and shot back in her native tongue. "Why movies? Why not?" Kunis testily replied. "What kind of question is that? Why are you here?"

While the room erupted with laughter, Timberlake could do nothing but sit there dumbfounded until the translation was relayed to him via an earpiece. When he finally received it, he pointed at Kunis and quipped, "This is my bodyguard."

This is not the first time Kunis has busted out Russian in public. During a 2008 press conference for the action film "Max Payne" at Comic-Con, an audience member asked what the Russian translation to a well-known expletive was.

"Friends With Benefits" is the latest in Kunis' burgeoning A-list film career which came about with her well-received role in the 2008 comedy "Forgetting Sarah Marshall" and the Oscar-winning "Black Swan" opposite Natalie Portman.

Later this year Kunis appears in the big-screen adaptation of "The Muppets" with "Sarah Marshall" co-star Jason Segel. She just started filming "Oz: The Great & Powerful" in which she plays evil witch Theodora.
