LOS ANGELES, Oct 1 — Emily Blunt is finally opening up about her breakup with ex-boyfriend Michael Buble.

The couple split in 2008 after three years together amid allegations that Buble had been unfaithful, and the actress admits although their split was “complicated”, she doesn’t feel comfortable discussing it.

“I don’t know, it’s complicated,” Blunt said when asked about the cheating rumours by Howard Stern on his SiriusXM show, exclaiming: “Now I’m going red because I never talk about it. I never want to talk about it.”

She did have kind words for her former flame, telling Stern that the pair “had a good time”. “I loved his family. I still do. I love his family,” she added.  

Buble has been open about the split, confessing earlier this year, “I was a jerk and I was careless and reckless with the hearts of women I was with.”
