Bradley Cooper and Jennifer Lawrence are together again! While they're still not a couple, the duo has been photographed together on the set of their upcoming movie.

The untitled project takes place in the '70s, which means both Bradley and Jennifer look much different than we're used to. While for Jennifer that mostly meant a change of wardrobe and an up-do, Bradley had to trade in his sexy, shaggy hair for some pretty intense curls (a la 1990s Justin Timberlake). Of course, if anyone can pull it off, well... the former Sexiest Man Alive would be it!

This will be the third film in which Bradley and Jennifer co-star together, but it will also include a bunch of other familiar names, including Christian Bale, Amy Adams and Jeremy Renner. While the flick isn't set to hit theaters until Christmas Day, you can still see the duo together in September, when their other film Serena comes out.

Bradley and Jennifer spent a lot of time together this awards season with all the hype surrounding Silver Linings Playbook, and were even rumored to be romantically involved, although they both shot down those reports. It seems that the world is generally in favor of these two becoming a "Brennifer," even with the 16 year age difference... though Bradley is currently rumored to be dating a 20-year-old model, so once again, our dreams are crushed.

Looks like these two will just stick to being the World's Greatest Co-Stars... which is totally fine, too!

What do you think of Bradley's perm?
