She was put up for nomination by the housemates' friends and family along with Dexter Koh, Charlie Travers, Sophie Lawrence and Jack & Joe Glenny faced the public vote.
But in the end, Hazel was saying her goodbyes, and facing a boo-filled chorus of 'Get Hazel Out'.
Bye bye: Hazel O'Sullivan becomes the seventh housemate evicted from the Big Brother house
'Not everybody gets to get into the Big Brother House so it's bittersweet,' the Irish model said. 'Never thought I'd last two months.'
She did realise that her relationship with Daley was the problem, but she complained that being in the house 24/7 means it's easy to go on any 'little bit of chemistry' there might be to avoid boredom.
She also blames Daley for giving 'so many mixed signals' and not admitting in the first place he had a girlfriend.
Release: Hazel shared her annoyance with Gina in the diary room during the day
Queen Bee Gina spent her time complaining that her workers were not flapping their wings as instructed by Big Brother, and took the opportunity to single out Hazel.
Asking the Irish model to do more 'buzzing'. Gina was given the middle figure, to which she replied, 'very classy, not a nice girl at all.'
Not impressed: Gina finally vented her annoyance with Hazel in a massive argument
No love lost: The two housemates threw swearwords at each other for a good amount of time'Just like you, you put the B in bitch alright!' Hazel retorted.
O'Sullivan then vented her frustration to Big Brother in the diary room: 'I would extinguish the bee in a second if I got the chance, there is no hiding of my dislike for Gina, I may have two days left in the house and my two days are not going to be ruined by Gina, I think she’s an absolute nightmare.'
And the fight escalated into a slanging match between the two, with Gina telling Hazel: 'You’re actually, literally a home wrecker, a class-less girl; I do not wanna have an argument with you, do not even speak to me. You’re a dirty-a**e skank and I want nothing more to do with you.'
Foul mouth: Hazel had no qualms commenting on Gina's appearance as insults
Bored: Charlie and Dexter didn't seem too impressed with the argument
Hazel didn't help herself either in the task as she lost the House £100 off the shopping budget as she failed to wear her shock pad for part of the task during the Day 1.
While Gina won £280 in the From A to Bee task, where she had to guess which housemate Big Brother refers to using housemate quotes.
I think the right person will go tomorrow hopefully anyway, or else I’ll be really angry.'
Unhappy bees: No doubt the tension in the house was putting a downer on the task
