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."
