“Supergirl” will be enjoying a full freshman season given CBS’ decision to add seven more episodes.

The additional seven episodes that CBS ordered will bring “Supergirl’s” first season to 20 episodes, according to The Hollywood Reporter (THR). The series, which was adapted from DC Comics, features “Glee” actress Melissa Benoist as Kara Zor-El, who is Superman’s cousin. The superhero series debuted a month after most shows were aired during the fall season.

The network’s decision to extend “Supergirl” to a full season came after the series achieved a 3.1 rating from the 18 to 49 age group during its premiere episode. The CBS series’ rating is now averaging 2.8. “Supergirl” also features more special effects than is usually seen in other television series.

The full season order for “Supergirl” is also an accomplishment for Greg Berlanti, executive producer of the series, according to THR. Berlanti has several superhero projects such as “Flash,” “Arrow” and the upcoming “Legends of Tomorrow.” He’s also a showrunner for “Blindspot” who was already renewed for season 2.

Meanwhile, Benoist has already shared her delight in getting a freshman season extension for “Supergirl.” The actress took to Twitter on Monday to share the good news. She wrote, “It really is a great day when you find out you get to wear a cape/fly around/and kick some a-- for a full season… yay @supergirlcbs !!!!”

The actress has donned on the red cape since the series premiered on CBS on Oct.  26. Benoist is joined by other stars such as Mehcad Brooks (as James Olsen), Calista Flockhart (Cat Grant), Jeremy Jordan (Winn Schott Jr.), David Harewood (Hank Henshaw) and Chyler Leigh (Alex Danvers). Apart from these stars, Benoist will also soon act alongside her husband Blake Jenner in the series.

Jenner’s casting was reported earlier in November by TVLine, where the former “Glee” actor is set to appear in several “Supergirl” episodes. Jenner, who will play Adam Foster, will also portray Benoist’s character’s potential love interest.

“Supergirl” airs every Monday on CBS.
