This will never actually happen, but we're okay with it because we kind of already know who's a good kisser – at least on camera.
See which costars kiss and tell, from Josh Hutcherson's game-changing smooch to Kirsten Dunst's less-sexy encounter with Brad Pitt.
On smooching: Jennifer Lawrence
There's just something so romantic about fighting to the death, are we right? "She's a great kisser – so, yup, the bar is high," Hutcherson revealed to Cosmopolitan of his The Hunger Games ally, whom he first puckered up to during the saga's first installment in 2012.
On smooching: Ashton Kutcher
If your first kiss was awkward or, you know, behind your school's gymnasium, try not to be too jealous of Kunis, who was introduced to the art of lip-locking in 1998 by none other than her current boyfriend, Kutcher. At the time, however, he was just her That '70s Show costar. "I was like, 'Oh, he's so cute – it's the Calvin Klein model!" the actress told PEOPLE in 2001. "Then I was like, 'I have to kiss him?' I was so nervous and uncomfortable. I had the biggest crush on him."
It's really hard being Emma Stone because you have to kiss guys like Andrew Garfield and Ryan Gosling, and then everyone wants to talk about it. Stone, who actually gets to smooch her The Amazing Spider-Man on-and-off screen love interest all the time, had the honor of comparing those makeout sessions to her Crazy, Stupid, Love kissing partner, Gosling, on The Ellen DeGeneres Show. "Apples and oranges, you know," she told DeGeneres in April 2012. "I love all fruit."
On smooching: Dakota Fanning
For the Twilight alum, sharing some on-screen P.D.A. in 2010's The Runaways, well, rocked. "It was cool. I didn't mind it," Stewart, who played the Joan Jett to Fanning's Cherie Currie, said while promoting the film. "The way that it happens in the script is so just a sort of moment in time and fun and natural and sort of impulsive."
You might want to sit down for this one: According to Dunst, kissing Pitt in 1994's Interview with the Vampire totally sucked. (Yes, we're talking about The Brad Pitt, who was named PEOPLE's Sexiest Man Alive not once, but twice.)
However, Dunst's assessment had more to do with their age gap (she was just 11 when they filmed) than his kissing prowess. "Everyone at the time was like, 'You're so lucky you kissed Brad Pitt,' but I thought it was disgusting," she told Bullett magazine in March. "I didn't kiss anyone else until I was 16, I think. I was a late bloomer."
