UPDATE 3:00 PM PT: An earlier version of this article erroneously listed 2015 C2E2 guests as 2016 guests, and has since been amended.


"Supergirl" fans have a lot to be thankful for -- not only was the CBS hit picked up for a full season last week, but series stars Melissa Benoist (Supergirl) and Chyler Leigh (Alex Danvers) are headed to Chicago in March for C2E2.

Benoist and Leigh's upcoming C2E2 attendance marks the first time the two will attend a convention together. They'll be at the pop culture convention signing autographs and taking part in their own panels -- though no official dates/times have been locked down as of yet.

Coming up on its seventh year, C2E2 2016 already has a sizable guest list, including Mike Mignola, Marguerite Bennett, Jose Luis García-López, Ming Doyle, Greg Capullo, Frank Cho and more.

The next C2E2 will be held from March 18-20, 2016, at McCormick Place in Chicago. "Supergirl" airs Mondays at 8 p.m. on CBS.
