Jennifer Lawrence is the latest star to officially sign on to star in Matthew Vaughn’s X-Men: First Class. Lawrence will play the character of Mystique in the prequel according to the report to THR.

Lawrence joins James McAvoy, Aaron Johnson, Nicholas Hoult, Michael Fassbender, Alice Eve, Caleb Landry Jones, Lucas Till and Kevin Bacon in Vaughn’s follow-up to the hugely successful Kick-Ass.

The buzz surrounding Lawrence’s role in Winter’s Bone has been non-stop since it won the top prize at the Sundance Film Festival in January, so I’m sure she will bring her own level of acting supremacy to the role.

X-Men: First Class will see Charles Xavier and Erik Lensherr before they were crowned as Professor X and Magneto, respectively. It will track their friendship, allies with other mutants as they work together to stop the greatest threat the world has ever known. During the process, a rift will come between Professor X and Magneto, the start of the eternal war.

X-Men: First Class is set to be released in 2011, and you can check our coverage here.
