Elizabeth Banks and Emma Stone ''would have a lot of fun''.
The 'Hunger Games' actress admitted she has locked lips with girls in the past, and opened up about her celebrity girl crushes.
She told The Advocate magazine: ''Angelina Jolie is always super hot, and Christina Hendricks is pretty ridiculous.
But I think I would have a lot of fun with Emma Stone ... I've definitely made out with a few girls in my time.''
The star - who has sons Felix, two, and Magnus, eight months, with college sweetheart Max Handelman - kissed 'Wet Hot American Summer' co-star Marisa Ryan in the comedy, but revealed it wasn't even in the script.
She added: ''With Marisa in Wet Hot American Summer, that kiss wasn't scripted.
''It was the second-to-last day of filming, and the director, my good friend David Wain, came up to us and said, 'Let's do one for the crew.'
''So that kiss was really just a fun and ridiculous gift for all the dudes on the crew.''
Elizabeth, 39, is a big advocate for gay marriage and equal rights and believes both celebrities and people in general need to ''be vocal'' on such subjects.
She said: ''It's a human rights issue. It's shameful that we don't have equal rights for our gay citizens in America. We should all be vocal about what we believe.''
