In a sit-down with Howard Stern on SiriusXM on Wednesday, Emily Blunt reluctantly fielded questions about ex-boyfriend Michael Buble. The former couple split in 2008 after three years together amid rumors of infidelity on Buble's part.
"I don't know, it's complicated," Blunt said when asked about the cheating rumors, exclaiming: "I'm going red!"
The Sicario actress did have kind words for her former flame, telling Stern that the pair "had a good time" and that she still loves his family.
"I never want to talk about it," she said of the relationship before eventually declaring: "I can't do it."
Buble has been open about his relationship missteps in the past,
telling Canadian entertainment show, eTalk
, earlier this year, "I was a jerk and I was careless and reckless with the hearts of women I was with."
But for Blunt, Stern had even more uncomfortable questions in store for their interview -- though she was surprisingly forthcoming when asked about whether an actor had ever become aroused while filming a love scene with her.
"Once," she confessed. "I think it's just better to laugh about it."
Though she wouldn't name names, Blunt did say that her co-star wasn't famous.
"I think the reaction was, we were filming and they shouted, 'Cut,' and I went, 'Oop!' and he went, 'Oop! Sorry.' And that was it ... We laughed about it, because I don't want him to be embarrassed. I think that would be unfair if I was like, 'Oh my God!'"
Asked whether she would go home and tell her significant other about the on-set encounter, Blunt's response was swift: "Oh God, no."
Today, Blunt is married to fellow actor John Krasinski and together they share a 1-year-old daughter named Hazel.
On-screen, Blunt plays an FBI agent opposite Benicio del Toro and Josh Brolin in the Mexican border drama, Sicario. In her interview on Wednesday, the 32-year-old also revealed that the film's original script called for her to get naked.
"We didn't agree to do it," she said, bluntly referring to we as "my t**s!"
"We're not doing it!" she declared with a laugh, noting that, "Benicio backed me up. It was a scene between he and I that was rewritten."
"It was never going to be rewritten," she clarified, before explaining, "But a financier approached Taylor Sheridan, the writer, and said, 'If you make her a dude, we will up your budget.'" She smiled flatly, "The sad state of affairs of this business."
