Emily Blunt and Michael Buble's relationship ended way back in 2008 -- but that didn't stop Howard Stern from bringing it up during his interview with the actress this week.

While promoting her new movie Sicario, Blunt's Howard Stern Show interview took a turn for the personal (as usual) when Stern brought up rumors that infidelity ended her three-year relationship with Buble.

"It's complicated," Blunt laughed, leaving the cheating rumors alone. "I never want to talk about it."

Blunt kept things nice when it came to her crooning ex, saying, "We had a good time," and emphasizing how much she loves his family.

Listen to the interview below:

Blunt is now married to fellow actor John Krasinski, while Buble married actress Luisana Lopilato.
