Well, that escalated quickly!
It's been a whirlwind of a few weeks for Miley Cyrus and her ever-changing relationships.
And on Tuesday her latest romance with Aussie singer Cody Simpson hit the next level as the 26-year-old confirmed things were getting serious, making reference to her "BF" on Instagram.
Over the past several hours, Miley has been sharing a slew of selfies after being hospitalised due to an unknown condition.
In one post, she makes her relationship Instagram official by captioning a snap of herself dressed in a hospital gown and lying in bed: "BF coming to visit me @ the hospy"
While she didn't detail what caused her to be ill, she earlier shared updates as she recovered.
"Trying to heal as quick as I can to make it to Gorillapalooz w @theellenshow @portiaderossi @brunomars this weekend!" she wrote.
"Send gooooood vibes my way! Hoping the rock star G-DS send me a boost of bad a-- and help me kick this sh-t to the curb where it belongs! We got gorillas to save!"
Miley called time on her marriage to Liam Hemsworth in August before enjoying a brief fling with Brody Jenner's ex-wife Kaitlynn Carter.
Following the women going their separate ways, Miley began seeing Cody, with the pair filmed sharing a sneaky kiss in LA last week.
Reacting to the footage being released publicly, Miley hit back on her Instagram Story.
"Can a girl not get a f**king açaí bowl and a morning make-out session in peace?!?!" she wrote.

Miley continued: "Men (especially successful ones) are RARELY slut-shamed. They move on from one beautiful young woman to the next MOST times without consequence. They are usually referenced as 'legends,' 'heartthrobs,' 'G,' 'Ladies Man' etc...where women are called sluts/whores!"
She also pointed out that Cody was Australian and therefore her type as well as making clear she was a fan of his age (22) and chiselled abs.
Since then, the romance has gone full throttle, with Cody referring to Miley as his "baby".
Cody, who also runs a poetry Instagram under the moniker "Prince of Neptune", has seemingly penned love poems for the Slide Away songstress.
The words to one poem read: "the moon's souvenir/ the boulevardier/ a ballerina on the promenade/ we open our curtains/ to the domesticated world/ for a natural hour/ spinning elvis records/ and making love/ in the soft jewelled morning."
Although he currently seems smitten, Miley is not Cody's first high-profile relationship; he also previously dated Victoria's Secret Angel Gigi Hadid.
