The Waterloo Road actress is busy learning lines and filming scenes for the BBC One school drama during the day, so has to practice with dance partner Pasha Kovalev at night.
Of her chances in the competition, Kovalev said: "[Now] Chelsee is starting to pick up the confidence she didn't have in the first few rehearsals.
"As a person Chelsee has an amazing sense of humour [but] the thing is, she's always tired because we always rehearse late at night."
Teasing her ballroom credentials, Kovalev added: "I have discovered that she has inner grace once she gets into the waltz position."
Strictly Come Dancing returns on Friday, September 30 on BBC One.
