The actress tells Ellen DeGeneres on Wednesday that her The Huntsman: Winter's War costar Chris Hemsworth is totally kissable – a revelation she jokingly finds frustrating.
"He's just the nicest guy in the world. Isn't he just the sweetest guy?" DeGeneres prompts Chastain, 39, on Ellen.
"Yeah, it's kind of annoying actually," Chastain responds. "Not only is he just perfect to look at."

The star jokes that the PEOPLE's Sexiest Man Alive alum's body is "disgusting," before listing more of his deplorable traits: "He's like a foot taller than me so he's probably 6'5, he's really funny and he's got the most beautiful, perfect family, and he's a great dad. It's just like, 'Ugh.' "
And, after some prodding from DeGeneres, Chastain dubs the actor from Down Under a "very good kisser."
"He's perfect, annoyingly," she says. "Elsa's a lucky woman."
Hemsworth is married to Spanish model Elsa Pataky, with whom he shares three kids: daughter India Rose, 3, and twin sons Tristan and Sasha, 2.
In The Huntsman: Winter's War, Chastain plays a hunter who re-teams with her former love Eric (Hemsworth). Of the film, Hemsworth told Elle, "It's a love story, essentially, between the Huntsman and his wife, who's played by Jessica Chastain, but it's also a road-trip movie. They team up and take off, them and a couple of dwarves, on a quest."
