Jenna Elfman will guest-star in the upcoming season of Shameless, AOL TV reports.
The Dharma & Greg star will appear in the second season finale as Jill, who has a dangerous past and, according to the network, "an awkward present" — whatever that means. No word on who she'll be interacting with, but the second season will take place during a sweltering Chicago summer.
Elfman, who appeared on the season premiere of Two and a Half Men, recently signed on for the next season of Damages.
Shameless is slated to return Sunday, Jan. 8 on Showtime.
