Cassidy has overwhelming popular support after she was given an ice-breaker task by Big Brother on the launch night, which involved her doing everything that she was told by Big Brother via an earpiece.
The actress's challenges included talking to Hollywood's Michael Madsen about Free Willy and kissing Frankie Cocozza on the lips.
Cassidy has 39.7% of DS readers' support at the moment, way ahead of nearest rivals Gareth Thomas (14%) and Denise Welch (12.7%).
Andrew Stone, Natasha Giggs, Nicola McLean and Playboy models the Shannon twins are currently at the bottom of the pile with the least support.
