There's a buzz online that Cameron and Justin are history, even though sources close to the couple say flat-out it's b.s.  Nonetheless, the talk is that Justin may have taken up with Lauren Popeil, the daughter of renaissance man/gadget guru Ron Popeil.

So we're thinkin'....if Justin does hook up with Lauren and it works out, what the heck do you get the couple that either has or has invented everything?!?
