Chicago Fire is about to heat up this fall, thanks to an impending guest star.

Serinda Swan (Graceland) has signed on for a quartet of episodes as Brittany Baker, a graphic designer who becomes a potential love interest for one of the key characters.

Based on previous quotes by producer Matt Olmstead, look for Swan’s Baker to cause romantic problems for Severide and Lindsay.

"There are competing interests that might pull them apart," Olmstead previously told TV Line.

Prior to her regular role on the aforementioned USA hit, Swan starred on A&E’s Breakout Kings and has also appeared on The Tomorrow People, Psych and Smallville.

Chicago Fire Season 3 premieres on Tuesday September 23 at 10/9c on NBC.
