How are the producers of Chicago going to follow up on the casting of Denise Van Outen as Roxie Hart? Top of the contenders’ list for replacements looks to be Claire Sweeney, star of TV soap Brookside. The Liverpudlian actress impressed viewers of Channel 4’s Celebrity Big Brother – in which six celebrities were locked in the infamous east London house for a week in March in order to raise funds for Comic Relief – with her singing skills during house challenges. Van Outen is currently continuing in Chicago to 15 September; Sweeney is expected to take over sometime later in the autumn.
