Celebrities don't just get half naked and pretend to be someone else for a living, no, they also help sell gadgets in their spare time. What troopers.

Behold GaGa, Fiddy and the very hirsute Adrian Grenier all peddling an assortment of wares at the 2011 International Consumer Electronics Show held at the Las Vegas Convention Centre yesterday.

50 Cent got to introduce products on behalf of SLEEK Audio, and doesn't he look happy about it. As does Grenier; he got to babble about the new Blackberry. He was later seen scanning the audience for his agent.

Then there was Lady GaGa, who honestly seems the most enthused of the bunch. Look at her there, showing how her assigned Polaroid products ("a mobile printer, an instant digital camera and camera glasses") work with finesse, a complete natural, in her techno widow get up.

In fact, she looks so happy and passionate about the whole thing, rolling up her sleeves and tinkering with her merchandise, I'll take 7 of whatever she's selling there, and triple the amount of camera glasses, just 'cause I'm easily swayed like that. Any celebrity endorsing anything, throw them in my direction, 'cause it's just the only way to sell things nowadays. Apparently. Why I've not purchased every one of Jordan's 15 books I'll never know.
