Ladbrokes said it had seen further support for Kemal to win and have cut his odds from 7/2 to 3/1.
Makosi has been cut to 6/1 from 8/1, while gay Tory Derek is cut to 8/1 from 9/1.
However, self-proclaimed sexaholic Sam is the favourite at 2/1 to be kicked out next following white witch Mary's exit on Friday. However, she may be saved by the sympathy vote after half the house ganged up on her and stole her make-up bag.
Betting on a 'Big Brother' bonk has been temporarily suspended after Vanessa and Lesley's late night link-up.
The two girls were seen together under the covers, but it is unclear if they were up to much more than trying to fool the camera.
Ladbrokes spokesman Waren Lush said: "We've suspended betting on a Big Brother bonk for the time being as we're not sure what went on under the covers between Lesley, Vanessa and Makosi. These lot swing more than a pirate shop at a theme park and it is too dangerous to bet when there is so much going on."
Elsewhere in the house, Maxwell is to be punished for breaking a house rule by either wearing a giant nappy or wearing a Tottenham Hotspurs T-shirt until further notice, after he burned underwear he was made to wear by Saskia after winning the counting task.
Maxwell spat his dummy out and burned the Spurs underwear in the garden, which Saskia chose to give the avid Arsenal an as part of yesterday's mission.
Busty Saskia was rewarded for winning the counting task by acting as Big Brother and being given the chance to secretly listen in on a fellow housemate in the Diary Room, of which she chose Maxwell, who describes himself as a "bit of a geezer".
Saskia must decide which of the punishments Maxwell will have to take, but she may spare him the giant nappy if she takes into consideration his words in the diary room when Big Brother asked him who he would want to stay in the house.
"Saskia, she's off the hook, gorgeous girl. Person I have the most laughs with. She didn't start off top of my list but now she's head and shoulders above the rest," he revealed.
