Jen Affleck is getting ready to bring her hater's heat to her performance tonight on "Dancing With The Stars," performing a contemporary number to Taylor Swift's "Look What You Made Me Do" with partner and Eras Tour dancer Jan Ravnik.

Last week, legendary pros Maksim Chmerkovskiy and Peta Murgatroyd called out DWTS for hiring Jan in the first place. “Jan has absolutely no business being a pro on Dancing With the Stars. There’s zero foundation, technique, quality, understanding of partnership. It is absurd,” Maksim said on The Penthouse with Peta podcast.
