The 24-year-old from Northampton has left the BB compound after displaying inappropriate behaviour.
According to reports, Big Brother made the decision to eject Aaron from the house after he continued to drunkenly flash his fellow housemate Joel Williams, after Joel had asked him not to. This is yet to be confirmed by Channel 5.
Viewers will be able to see Aaron's exit in tonight's highlight show.
With Aaron gone, one person who won't be pleased to hear about his exit, is his friend Gemma Collins after she had backed the model to win the show.
On his entrance to the Big Brother house just two weeks ago, Gem revealed that she and Aaron are actually really good friends and she had placed a bet on him being crowned this year's winner.
Taking to Twitter, G.C. shared her excitement over Aaron being one of this year's fifteen housemates, tweeting: "He will win @AARON_FREW my money's on him such a beautiful boy x."
She then added: "Off to the bookies in the morning I know already @AARON_FREW is gonna tear the house up and win #aarontowin," she said.
Aaron's departure comes after Big Brother revealed a major nominations twist for tomorrow night's live eviction show.
Earlier this week, six housemates had been nominated - including Aaron - and believed they would be facing the public vote.
However, Big Brother soon revealed the nominated housemates are actually safe and those who weren't put up for eviction will now do so, instead.
As a result, Amy and Sally Broadbent, Harriet Jackson, Chloe Wilburn, Kieron McLeod, Sarah Greenwood and Danny Wisker will now face the public vote. Although, they do no know this yet. Jack McDermott - despite not being nominated - will remain safe as he chose to use one of three immunity passes he won during this series' launch night.
Not only will there be an unexpected eviction tomorrow night, but FOUR of the unaware housemates will get the boot and FOUR brand new housemates will replace them.
Channel 5 has confirmed that the four chosen housemates will still be evicted as planned, following Aaron being removed from the show.
Big Brother airs nightly on Channel 5.
