Love is officially dead.
Taking to Instagram on Friday, the 38-year-old said she gave the relationship her "best shot" but it simply "didn't work out."
"I don't know how to explain this because it's an unusual circumstance to be in," the post began. "But because I entered this relationship so publicly, I know I owe an answer to Australia about my personal life."
"I went into this experience looking to settle down and start a family," she continued. "I gave it the best shot I could and my intentions were everything I said I was looking for, but unfortunately it just didn't work out."
"As much as I respect him, we are just very different people," she wrote in the early-morning post. "There were no contracts or pressure to stay together whatsoever from anyone and we remain friends."
Their road to romance started away from the cameras when the former popstar-turned-actress-turned-radio-presenter-turned-reality-TV-star was asked out by the millionaire pub owner.
Soph turned him down because she was "too hungover" but really, she just thought he was a "douche."
But Stu refused to take no for an answer and instead of just calling her up and asking her out a second time, he chased her to the ends of the earth by signing up to be an intruder on The Bachelorette, 2017.
Yep, Stu Laundy and Sophie Monk's love story on The Bachelorette was anything but conventional and from the beginning the odds were stacked against them with persistent speculation their relationship was a showmance.
"I think because they expect us to be almost making out, like the show. We are very affectionate when the cameras aren't around. He's got kids as well, we're not going to be all over each other," Sophie insisted over their lack of public PDA.
Break-up rumours reached fever pitch after frosty photos emerged of the couple fighting during their Christmas break in Canada and it looks like that was to be their final public outing together.
As Sophie and Stu announce their sad split, we look back at their romance in happier times!
