Joan Collins may or may not think Jennifer Aniston is “beautiful” but even Joan may have a hard time believing, like the rest of us, that a simple pair of glasses would turn the adorable Aniston into a frumpy nerd.

But that is exactly what we’re supposed to buy with Aniston’s eyeglasses-wearing character on her upcoming movie, Just Go With It, co-starring Adam Sandler, Kevin Nealon, Dave Matthews and Nicole Kidman.

Sandler plays a plastic surgeon womanizer and Aniston his assistant-slash-best friend who will help him leave behind his womanizing ways to land the woman of his dreams. Of course, Aniston will do this by becoming an overnight bombshell herself, simply by ditching the eyeglasses ala Clark Kent.  I love both Sandler and Aniston, so, I will see this movie for sure despite the fact that I just don’t think Aniston could play off a nerd.

Watch the trailer below and let me know what you think.  Just Go With It hits the theaters in time for Valentine’s Day on Feb. 11, 2011.
