Sharon Osbourne reportedly "snapped" at London's Heathrow airport on Tuesday.
The X Factor UK judge happily journeyed through the travel centre until she tried to pass through security.
As officials tried to put her liquid items in re-sealable bags Osbourne is said to have thrown an absolute fit.
"Sharon was livid that they were poking around in her bag, because she said she had used it several times before," an eyewitness told British newspaper The Mirror.
"She lost her temper with them and snapped, 'Fine. Just leave them then. I don't want any of them. I don't care.'
"Then, she stormed off leaving some shocked-looking security guards with all her toiletries. Loads of other passengers were staring."
Apparently soon after the episode Osbourne realised she needed some of the items in the discarded bag.
She then tried to retrieve her belongings to no avail.
"Five minutes later, she sent an assistant [to] ask for the bag back," the onlooker detailed.
"She explained that it had her medication in it.
"Sharon turned up while the staff were explaining that they had destroyed it and its contents, and got angry all over again.
"But now, she was even angrier, because she said she needed her medicine. She was really ranting, but there was nothing anybody could do because it had been thrown away."
In April Osbournes daughter Kelly also reportedly had a "paranoid outburst" with an Australian journalist.
At the time Osbourne's husband and Kelly's father Ozzy admitted he relapsed on drugs and alcohol.
It has been claimed that Kelly Osbourne also unleashed an invective on an Australian morning radio show about her father.
Kelly is believed to have ranted at security, calling one man a "first class t**t" at Star casino because they asked questions about her United Kingdom driver's licence.
