The latest rumours from ongoing talks suggest there's a battle over budget behind the scenes.
Channel 5 is said to been keen to keep the show on air, but only at a much lower cost.
"We all know the show is never going to return to its heyday and everybody is fine with that," a source said this week "It doesn't matter so long as there's still some people who do still watch it."
The source explained: "It brings in viewers, but it's not a cheap show to make, especially as many of the shows on Channel 5 bring in similar audiences for a fraction of the cost.
"When BB is on there's 600/700 crew who work on this behind the scenes, transmitting each day, filming 24/7, maintaining the house etc."
They added: "It costs a lot of time and money but I'm sure we'll sort something out."
Insiders last month played down claims that the show was definitely headed for the scrapheap, insisting that negotiations between Channel 5 and programme makers Endemol were far from over.
Deadline said that there was "no truth" (yet) in the rumours that the show has been axed.
"Both companies are still in discussions over future series when the contract for the house-based entertainment format ends later this year," they added.
A spokesperson for Channel 5 said: "Channel 5 are committed to a further series of Big Brother and of Celebrity Big Brother later this year."
While we await news, bookies have made it just a 2/1 shot that Channel 5 confirm this summer's series will be the last.
However in some good news for BB fans is that it's just 6/1 for the show to switch platforms to Amazon Prime, while 10/1 says Netflix strike a deal.
Alex Apati of Ladbrokes said: "It looks as though Big Brother may have finally run its course, with odds of the show getting scrapped now at record lows."
Big Brother is expected to return to Channel 5 in June time.
