Flashy gadgets and gizmos won't all that's on display at the annual International CES in Las Vegas this month. Amid the consumer tech, attendees will once again find themselves with the chance to gawk over the event's celebrity guests.
Some of these celebrities will add their star power behind specific brands, though celebrity cameos have backfired in the past, with some people remembering their appearances more so than the brands they represented. For example, pop star Justin Bieber attended in 2012, but do you remember which brand he tried to help promote?
