The 27-year-old, originally from Melbourne, Australia, was the first of three extra housemates shoved into the house in week five following Geordie Jen's eviction.
The Angelina Jolie look-alike said she was praying she would find her Brad Pitt in the house since she's never been in love - or even had a committed relationship.
And she certainly tried her best to win her Prince Charming - although she couldn't seem to decide which one of the housemates that would be.
The personal assistant left the others baffled over her sexuality after she told them she was attracted to both men and women - but then later claimed she had been kidding.
She added to the mystery a day later when she and Kathreya swapped spit in the pool after encouragement from their fellow housemates. "Kat wants to kiss me," teased Sara as they swam about, prompting Rebecca to chant: "Snog her, snog her!"
Kathreya insisted she felt "scared" and Darnell laughed, joking: "Sara can't get no action!" "F**king hell," Sara cried, "What's wrong with me? I actually feel humiliated."
But she wasn't embarrassed for long - because the girl-on-girl pair took the plunge with a steamy clinch.
But she soon ditched the Thai masseuse, and turned her full focus to snagging Stuart.
She confessed to Rebecca she had a massive crush on the beefy single dad, asking her if she had a chance with him. She set about flirting with him in a bid to win him over - but even her incessant eyelash batting failed to get him to really notice her.
As they sat together on the couch, Sara gushed: "I can't believe you can't find a girl. Tonight you look cute. I think close up you look more adorable. I think you're quite opinionated and I quite like it. You put yourself down a lot, you're not a minger."
Although the personal trainer appeared pleased to be lavished with compliments, Darnell was far from happy with all the time Sara devoted to Stu.
The pair no longer spoke to one another after Sara hopped out of Darnell's bed and into Stuart's in week nine.
Darnell was so embarrassed by her rejection and her claims he wanted to have sex with her, he jumped over the barrier into Hell, where he slept for the night.
They later tried to clear the air, with Sara brushing off the situation by insisting she had been joking around - but Darnell was deeply hurt.
Two weeks later, he was still furious over the incident, and sent Sara running to the Diary Room in tears after calling her an "ugly bitch". Darnell said: "I'm not going to lie, we do not get along. As soon as we start talking to each other again, we don't get along.
"She made me look like a pervert on national television. F**king bitch." Finally, in the penultimate week Rex and Darnell were reprimanded by Big Brother for bullying Sara, after Channel 4 was flooded with over 1,500 complaints.
But Sara had other things to worry about. She and Lisa were put up for eviction during a nomination face-off. They received the most votes as the housemates were told they must vote in front of each other during a surprise twist.
However, it wasn't all doom and gloom. Sara and Lisa each became £25,000 richer after playing a game of Prisoner's Dilemma. They were told because they received the most votes they had the chance to win £50,000 - but they both decided to split the winnings. With a prize like that, we're sure Sara could woo Stuart with a cracking night out!
