'Chicago Fire': Renee Finally Comes Clean About Her Pregnancy With Severide (VIDEO)

Clearing the way for her transition to a full-time cast member on "Person of Interest ," Sarah Shahi's Renee finally came clean to Severide on "Chicago Fire ." She'd told him she was pregnant and that he was the father, leaving him questioning his future.

This babys not yours," Renee confessed. "I know how crazy this sounds, but I wasnt lying to you. And I actually convinced myself that it was yours. It was ours.

It turns out that Renee had a one-night stand while she was in Spain trying to get over Severide. It was that chance encounter that had led to her pregnancy. And so, as expected, she packed up her things and moved out. On the way out, she told Severide that he would make a great father someday.

Series star Taylor Kinney summed things up on Twitter by writing, "Baby mama drama." But now that it's someone else's baby, it's drama that won't impact "Chicago Fire" quite so much.

The baby-mama-drama-free "Chicago Fire" continues on Tuesdays at 10 p.m. ET on NBC.
