Mila Kunis says kissing Natalie Portman was like "nerd heaven".
The two actresses share a kiss in the forthcoming ballet dancer drama Black Swan and Mila - who is dating actor Macaulay Culkin - is already tiring of the attention the scene is attracting, but admits she understands why people are so interested.
She said: "It's two girls making out and guys have a thing for that - it's silly but I can see why people care.
"Natalie is like every guy's dream. She's a nerd's idea of heaven."
Natalie has also spoken out about the scene, saying that it is an "extreme" moment.
She said: "It's a very extreme movie, it's like very extreme situations. It's not explicit in any way."
While Natalie had no problems locking lips with Mila, she says it was "hard" having to smooch both Tobey Maguire and Jake Gyllenhaal in her latest movie Brothers.
She said: "I'll be murdered if I say who was the better kisser. I'm probably the source of envy for getting to kiss both of those boys. It's hard to be me."
The 28-year-old actress also said she is now making a special effort to work on more demanding film roles in a bid to shed her "cute" title and embrace adulthood.
She explained: "I'm trying to find roles that demand more adulthood from me because you can get stuck in a very awful cute cycle as a woman in film - especially being such a small person. I'm a really late bloomer. In my own life, it's only been the last couple of years where I'm like, I'm an adult."
