Paul O'Grady has become the latest name to turn down a hosting stint on The Nightly Show.
The new week night ITV series began at the start of the month and airs at 10PM each evening between Monday and Friday.
Each week a different host is in charge with David Walliams, John Bishop and Davina McCall at the helm so far.
The Sun reports that Paul O'Grady, who previously had his own chat show on ITV, was approached but couldn't take up on the role.
A source said: “Paul was approached at the end of last year but he wasn’t able to do it."
The news comes as ratings for the series dropped to their lowest ever this past week.
Former Big Brother presenter Davina started her five days in charge with the lowest Monday numbers before viewing figures dipped to a record low on Tuesday.
Numbers rallied slightly on Wednesday and Thursday - although still well down on the equivalent episodes in the first two weeks - but collapsed again last night.
The show dropped below a million viewers at 10PM according to overnight viewing figures, with 990,000 tuning in for the Friday episode.
Overall, Davina's week as host averaged 1.3 million viewers, down 400,000 on John Bishop's previous average last week.
The Nightly Show returns all next week at 10PM on ITV with Dermot O'Leary in charge while Ant and Dec are set to also appear in a bid to increase ratings.
