Jennifer Lawrence Asks Chris Pratt: 'What's Your Favorite Part About Me?'

“Honestly, her sense of humor," Pratt answered.

“This is really tough to ask. I'm kind of embarrassed,” she began in a surprise video message for Pratt on “Good Morning America.” “What's your favorite part about me? If you had to choose. And be specific.”

The “Jurassic Park” actor pondered for a few seconds before giving his response to his “Passengers” co-star.

“Thankfully, she’s beautiful on the inside,” he said. “Honestly, her sense of humor. She’s really, really funny. She totally rolls with the punches. She’s genuinely hilarious. We laughed every day, all day making this movie.”

Pratt and Lawrence star in the upcoming science fiction film, in which they’re traveling through space but wake up 90 years too soon after their ship malfunctions.

Being such a small cast, Pratt and Lawrence got very close on set. He’s been teasing her fans on social media by intentionally cropping Lawrence out of his photos.

“She’s not social media, so I don’t think she really know what’s going on,” he joked. “But she’s got such a very passionate fan base and they’re hitting me on up on Instagram and Twitter and stuff like, ‘Please give us photos of Jen. We just want photos so bad of Jen.’ I just can’t help but have a little bit of fun with those fans.”

Pratt promises there is a “really great photo coming up,” on his Instagram, “so stay tuned.”
