Ezra’s baby brother is striking out on his own! Pretty Little LiarsGregg Sulkin (Wesley Fitzgerald) just started filming on his new show, the hotly-anticipated television adaptation of the young adult book series, Delirium. And, judging by the on-set pic he just tweeted, he’s just as excited as we are at the prospect of this series!

FOX's Delirium is set in an alternative present-day Portland in a world where people have been indoctrinated to believe that love is a disease, or “delirium,” that lies at the root of all social problems. Gregg will play Julian, the son of a top political leader and love interest to protagonist Lena, to be played by Emma Roberts.

The cast and crew of had the read-through for the pilot last month, as reported by Just Jared, and it looks like filming is now underway. The pilot has been ordered by Fox, which means they will have final say on whether the show goes to air. We’re hoping - for Gregg’s sake, as well as our own - that we have a chance to catch Delirium.
