Michael Buble has been a hot topic of conversation this past week–at least where actress Emily Blunt is concerned. The two dated for three years prior to his relationship and subsequent marriage to Argentinian model Luisana Lopilato.

During the last of his time with Blunt–as well as after the two split up–rumors ran rampant about Michael Buble having cheated on the Sicario actress.

Howard Stern brought up the topic of the Michael Buble cheating rumors when Emily Blunt was a guest on his radio show Wednesday.

“I don’t know, it’s complicated,” Blunt admitted. “I never want to talk about it. I can’t do it.”

She added, however, that the two “had a good time” during their time together. The actress also revealed she still loves Michael Buble’s family.

“I loved his family,” she said, after Howard Stern brought up how Michael Buble brought her o Canada to meet his mother.

“I love his family. I still do,” she clarified.

Michael Buble and Luisana Lopilato have a two-year-old son, Noah. Emily Blunt–now married to actor John Krasinski–has a 19-month-old daughter named Hazel.

Do you suppose Michael Buble really cheated on Emily Blunt? Why do you suppose she refused to discuss the situation–now at least seven years in the past? Emily Blunt and Michael Buble dated from 2005 to 2008. It would seem even bad memories would be distant ones by now.
