IM A Celeb has lost more than five million viewers since the start of the series amid mounting complaints about the dull line-up.
The first episode fronted by Ant and Dec last month pulled in 10.63 million, but just 5.46 million saw Saturdays show.
And to make matters worse for producers, each nights programme is averaging 1.23 million fewer than its equivalent episode last year.
An industry source said: Seemingly, some viewers havent stuck about after seeing who was taking part.
There are some great names in Caitlyn Jenner and Ian Wright, but with every big star there must be lesser-known people and some viewers think there are just too many unknowns.
There hasnt been heaps of drama and viewers look to be turning off in quite large numbers at the moment.
And viewers have also noticed a huge lack of sexy scenes after the shows female stars opted to stay away from the camps iconic waterfall shower.
Which has proved a hit in previous years thanks to campmates including Myleene Klass and Vicky Pattison.
Sunday nights show saw unknown comic Andrew Maxwell get the boot, having followed Radio 1 DJ Adele Roberts out of the jungle.
Minor squabbles have seen former footballer Ian clash briefly with Andrew, and James Haskell accusing Kate Garraway of stupidity but little to really get viewers talking.
In fact, there has been more drama away from the cameras after Jacqueline Jossa was allowed to make contact with husband Dan Osborne over claims he cheated on her with campmate Myles Stephensons ex Gabby Allen.
The allegation prompted the ex-EastEnders star to break down and remove her wedding ring.
