Jimmy Kimmel and Emily Blunt’s families are pretty close — they vacation together, have dinner together, pull epic pranks on one another — and, it turns out, the actress has an incredible and hilarious mother, at least according to the late-night host.

During Blunt’s appearance on “Jimmy Kimmel Live!” to promote the upcoming “Mary Poppins Returns”, Kimmel recounts a story about her mom, Joanna Mackie, whom the actress calls his “favourite person.”

“I love your mother,” Kimmel, 51, says as Blunt, 35, responds, “Why are you so obsessed with my mum?”

It turns out the feeling is mutual.

“She really likes you. She reserves this compliment just for people she really likes, she goes, ‘Jimmy is such a honey, isn’t he?'” Blunt tells the audience as Kimmel shares an embarrassingly hilarious story about Mackie that involves a spaghetti dinner made by the “Mary Poppins Returns” actress.

“She takes a forkful of pasta and I notice that there’s a hair…One of your hairs, probably,” Kimmel says, recounting the dinner with the two families. “It was a little ‘Hairy Poppins’ in the pasta and your mother, without missing a beat, maintained eye contact with me and maintained a conversation with me and I could just out of peripheral vision see her wrapping the hair around her finger very neatly and then it disappeared.”

“I couldn’t wait to tell you about this,” Kimmel says.

“That makes me feel a bit sick, actually,” Blunt replies, miming pulling a hair out of her mouth. “You’re her kid. You’ve probably thrown up in her mouth,” he adds.
