According to Hollywoodlife.com, the Biebs asked his campaign co-star Lara Stone out on a date during their shoot, and was shut down. Why? Because she's married. LOL!
Justin apparently didn't know she was a taken lady. A source told the site, "While they were doing the whole Calvin Klein ad, Justin was very forward and asked Lara on a date. He made it look like a joke at first, but then tried to put in the charm. It didn't work though as she respectfully declined since she is married. Surprisingly, it didn't get awkward and the shoot went on without incident."
At least all of that didn't mess up their hot pics. They seemed to turn out just fine. You can see those, here.
We aren't surprised by Justin's brave ways, either. He reportedly asked a not-so-single waitress out while in Hollywood a few weeks ago, too.
