Brad Pitt, Angelina Jolie, Robert Pattinson & Kristen Stewart Will Attend Cannes Film Festival

Sounds like the 2012 Cannes Film Festival is bringing out Hollywood's hottest couples! From the newly-engaged Brad Pitt and Angelina Jolie, to Twilight's real-life couple Robert Pattinson and Kristen Stewart, get ready to be wowed by red carpet PDA! 

The lineup for the 64th annual Cannes Film Festival was announced today and some of our favorite stars will be promoting their films in France from May 16 to May 27. 

Aside from Branglina and Robsten, a pregnant Reese Witherspoon and her hubby Jim Toth will walk the red carpet, along with other A-list couples like Matthew McConaughey and Camila Alves and new parents Bruce Willis and Emma Heming. 

And how could we forget about our favorite hunky heartthrob, Zac Efron, who is confirmed to attend the prestigious event as well.

OK! NEWS: KRISTEN STEWART TALKS "AWESOME" SNOW WHITE & THE HUNTSMAN IN NEW TRAILER! 

Brad will be promoting his new project, Killing Me Softly, this year, while Rob and Kristen will be supporting their movies, Cosmopolis and On the Road. We're not sure if the couple will walk the red carpet together at their separate premieres, but we sure do hope so.

If not, we can always bet on Angie standing by her man and showing off that stunning engagement ring of hers!
