Dancing With the Stars Season 18, Week 4 was the Switch Up, and Cody Simpson was paired with Sharna Burgess. Australians together! They have the Foxtrot.

Cody is by far the youngest partner Sharna has had. She feels the generation gap. She is not OK with his droopy pants. She doesn't put up with his messing around. Sharna wants to make sure he shows progression. She's focused on the frame.

Cody starts the dance by singing, but then goes into a pretty traditional Foxtrot. He clearly has been working on his frame. His footwork is decent. Sharna sells the heck out of the performance.

Bruno says that when Cody is side-by-side it's great, but he needs to work on the hold. Carrie Ann says he needs to move from the core. Len agrees. He's good when he channels "his" style, but needs to work on the details. Julianne says to get to the top, Cody needs to embrace ballroom style.

Score: 31/40.

Dancing With the Stars airs on Mondays at 8 p.m. ET/PT on ABC.
