After a strong premiere episode that saw her dance the Viennese Waltz and leave everyone in tears, Selma returned for another strong week.
The Cruel Intentions star and author appeared on Elvis Night to dance the Jive with her partner Sasha Farber to the classic Jailhouse Rock.
The judges once again gave them strong reviews, praising Selma for pushing through her health struggles and even pulling out a surprise cartwheel and split.

The camera panned over to her left in tears as her friend pushed through her multiple sclerosis diagnosis, even supporting Selma's 11-year-old son Arthur, who attended both shows to cheer his mom on.
