Celebrity Big Brother contestant Aubrey O'Day has been given a formal and final warning after spitting in Stephen Bear's sandwich.
The former Danity Kane singer was reprimanded by Big Brother for "unacceptable behaviour" after Bear ate the contaminated snack.
Aubrey had to prepare the sandwich and cup of tea for Bear as part of a task which saw the housemates divided into two groups, with "The Artificials" assigned to complete tasks for members of "The Humans".
In the Diary Room, she explained that spitting in Bear's food had been intended as a joke. She apologised and was given a final warning.
But Bear was philosophical about the incident, telling Big Brother: "She spat in my tea, big deal! I'll probably put her up for nomination every single week. I've had worse in my mouth!"
Apologising, Aubrey told Bear: "I'm sorry. It was not done in a malicious way."
Bear gave her a hug, saying: "If you want to kiss me that bad you can."
In scenes which will be aired in Wednesday's episode, X Factor reject Chloe Khan will also be shown pranking Heavy D.
Chloe poured water in the Storage Wars star's shoes and spread chilli powder and suntan lotion on his side of the bed.
She had been unhappy that Heavy D, as a "Human", had asked her as his "Artificial" to wash his underpants.
But when Mob Wives star Renee Graziano heard about the prank, she warned Heavy D's bedmate Bear "not to sleep in his bed" because of the mess.
After finding out about the incident, Heavy D thought Bear was the culprit - but was forced to apologise when it was revealed that the prankster was actually Chloe.
Celebrity Big Brother airs at 9pm on Channel 5.
