Yep, your fave tween couple have called it quits after seven months of dating. Boo-urns.
They both announced the news of their split on Instagram stories with near-identical explanations for their break-up.
"The decision with Jacob and I was completely mutual. We are both happy and remaining friends," said MBB.
Jacob wrote: "The decision w mills and I was completely mutual. We are both happy and remaining friends."
The pair, who started dating in January, have had their fair share of dramz throughout their relationship.
In April, Jacob Sartorius got exposed by a couple of different girls online for doing the dirty behind Millie's back. While in London, he badgered a fan to send him nudes, while also asking for them from music video co-star Morgan Cryer.
While Millie initially deleted all the photos she had with Jacob on her Instagram, she later violently backtracked and posted a photo of the two together.
It's been real, guys.
