The teatime chatshow host recently threatened to leave the broadcaster over plans to cut his programme's budget by half.
According to the Daily Express, executives are now "hastily" considering their options for the 5pm slot amid fears that O'Grady will not return when his contract expires at the end of the year.
The newspaper has suggested that Loose Women star and former Dancing On Ice contestant Coleen Nolan is one of the names being put forward to replace the Birkenhead-born comedian.
Meanwhile, actor Shane Richie, who is Nolan's ex-husband, has also been tipped as a possible successor.
O'Grady moved his chatshow from ITV to Channel 4 in 2006 following a feud with his former employers.
