Being a Brit I'm no expert on American talk shows. I sure am familiar with Tim Allen though and it looks like the gadget loving movie star is rocking the BlackBerry Passport - and liking it.

When it comes to good publicity you can't beat something like this. I'm not sure how many million people tune into the show but I do know it's huge.

As you'll see, the pair have a bit of fun regarding the size of the Passport, but that's not surprising. I would expect people who are not familiar with the device to be a little freaked out by it - not just because of it's big square shape but in many places, particularly the U.S. it's not as common to see someone with a BlackBerry compared to the likes of the iPhone or a 'Droid'.

Let's hope we see more celebs falling for the Passport. Wouldn't it be great to see them all switching to the device? Will it happen? Only time will tell.
