Michael Buble and Leon Jackson sing Lost together in Scotland Glasgow SECC on July 19, 2008 on X Factor.

Michael Bublé (32) and Emily Blunt (25) have finally broken up after a three year relationship. Michael’s mom, Amber Bublé (53) said just a few months ago:

"I love her [Emily]. In fact if he doesn’t marry her, I’ll kill him. But we’d find someone in the family to marry her because we’re not letting her go, ever. She’s just the best thing ever and they’re perfect together."

In November of 2007 pictures surfaced showing Buble allegedly cheating on Blunt with Tiffany Bromley, who provided pictures of the two together, and another of Buble sleeping on her bed. Click here to see the pictures. With the cheating allegation public it’s a surprise Buble and Blunt lasted very much longer. His mom is probably more disappointed than anyone.

Michael Buble is accused of cheating on his girlfriend Emily Blunt by the alleged other woman Tiffany Bromley. To prove her allegations Tiffany took the pictures you see here. Entertainment Wise reports:

Emily Blunt’s boyfriend Michael Buble has been branded a love rat by a blonde who claims to have been enjoying secret sex sessions with him behind the actress’s back.

Tiffany Bromley, 28, says she has been bedding the Canadian singer on and off for the past decade – and even romped in the flat he shares with the star of The Devil Wears Prada.

Bromley tells the Globe: "Michael is a cheater and a rat. We’ve made mad, passionate love a couple of times since he and Emily have been together. The last time was August 17 in the apartment they share in Vancouver."

The blonde rates Buble "an 11 out of 10" in bed – and says he once suggested a threesome.

She adds: "I told him, ’No way!’ He said, ’Don’t knock it till you’ve tried it. You don’t know what you’re missing.’"

Bromley claims that she hasn’t seen Buble since she took camera phone photos of him sleeping and then took off wearing one of his designer shirts.

Tiffany Bromley sounds like she got dumped because Michael was getting serious with Emily, so Tiffany got jealous and went psycho and sent these photos to anyone who would post them. Too bad Tiffany doesn’t have a time/date stamp on the photos. All Tiffany has proven is that she is a psycho. Now we’ll see if Michael or Emily even care enough to respond. It’s really no surprise Tiffany is jealous, Emily is a lot hotter than her.
