JJ coming back to Criminal Minds for Season 7 and 8

Criminal Minds fans and specially those who are fans of SSA -Media Liaison Jennifer "JJ" Jarreau (that includes me) will be delighted as A.J. Cook has sign on to return to show as the series regular for two seasons.

This would be a great news since they need another female agent on the team and there no one more suitable than JJ herself. She will also be a good compliment to new agent Ashley Seaver (played by Rachel Nichols) as she is basically Emily Prentiss' "replacement".
