The cuteness.

Millie Bobby Brown has been absolutely killing it at the moment. From her stellar performances on Stranger Things, to her jam-packed media schedule, and not to mention she's totally slaying red carpet style... it's safe to say she's a busy little woman. However, the 13-year-old made things Insta-official with her boyfriend last night... and we just don't know how she fits it all in! The actress shared a black and white picture on Instagram Stories of her cuddling up to her new man on New Years Eve. She is beaming in the photo and simply captioned it with three red hearts. So, who is her boyfriend and what exactly does he do? Well, according to Hub, his name is Jacob Sartorius and he's 15-years-old. Jacob hit the big time by creating lip-sync videos on the site Musical.ly, before transitioning into the pop music industry. He's best-known on YouTube, and his music videos regularly rack up tens of millions of views. Rumours that the pair have been dating have been circling for months now, especially after Millie posted a photo of herself cuddling up with a teddy bear and captioned the photo: "Thanks for the bear" along with a red heart. Jacob commented on the snap, simply saying, "Of course." Anybody else getting young Bieber vibes from him?
