Like John Mayer, Cooper has a reputation for preferring fun over serious, longterm relationships. The Hangover star was linked to Aniston all the way back in 2009 and then again in 2011. Since neither has really addressed the dates publically, we donít know whether there was ever any legitimate attempt to make this work from either end, but if public opinion is any gauge, itís probably a good thing this one didnít last. After Brad left her, sympathy for Jen was at an all-time high. The goodwill carried through the Vaughn relationship too, but once Cooper and Mayer entered the fold, many fans began to wonder if she was trying to find lasting happiness or shooting to have transient good times.
