While speaking to E! News about her upcoming crime-thriller, the 28-year-old Portland native couldn't help but sing praises about her hunk of a co-star.
"He's an absolute dream to work with. I can't believe how down to earth he really is. He's so talented. It was so much fun to work with him," she said of Reynolds.
"He's playing an really odd character," she continued. "He is not all there all the time, and its amazing how as an actor he can be so present and so giving to all the other actors even though he's playing this character who's not always in touch with reality."
As for Reynold's wife, the Academy Award nominated actress said she was just a star-struck with Lively's charm as everyone else.
"She's just heaven! She's so kind and so stylish," Kendrick said of Lively.
"Every time I would see her wear a new nail polish color, I'd be like, ‘I'm going to wear green nail polish like her!' But then, damn, it doesn't make me look like Blake Lively. So close!" she joked.
The Voices, a Marjane Satrapi film about a factory worker who hears advice from his pet dog and cat and winds up implicated in a murder, hits theaters on October 3.
