It was the former Disney princess who got the 1D star into bed. Before One Direction fans go wild with jealousy, let's clarify that Miley was cuddling up with a cardboard cut out of Harry.
Cyrus posted the tongue-in-cheek snap online. In the picture, Miley lies next to a one dimensional Styles in a massive king size bed, a faux fur blanket is draped over the pair.
The singer clutches Harry and stares adoringly at his face. The picture immediately caught the attention of Miley's Twitter fans and followers. "I have a cut-out of him too," one follower excitedly wrote.
Miley also posted several photos of her friends holding One Direction fanzines.
Yesterday, Miley's younger sister Noah celebrated her birthday.
Noah is a hardcore One Direction fan and Miley spent the day getting up, close and personal with some of the band's merchandising.
In another snap Cyrus and her little sister pucker up and get ready to kiss the cut-out. Miley tweeted that all her sister want for her birthday was Harry Styles.
But soon, the internet was buzzing as hoards of teenage girls speculated whether Miley had a secret crush on Styles.
Cyrus is engaged to Australian heartthrob Liam Hemsworth and stated that the twitter post was in no way designed to entice Harry.
"In no way do I want Harry," she wrote. "No offence. I'm happily engaged. Just got saucy with a cardboard cut-out."
Styles and Red singer Taylor Swift (23) called time on their whirlwind romance days ago. The pair hit it off backstage at the X Factor.
They took romantic weekends away, visited the zoo and Taylor had even introduced Styles to her parents.
But, alas, their beautiful romance was not to last. The two ended their relationship after what has been described as the mother of all rows on a not-so romantic weekend away.
Styles and Swift had jetted off to the British Virgin Islands on New Year's Day after spending Christmas apart.
But things did not go to plan and Taylor flew back alone to the US after just three days. Harry stayed on and partied with bikini- clad girls on Richard Branson's Necker Island home, as you do.
According to sources close to the band, trouble was on the cards for a while. "Harry felt Taylor was nagging him," one source said.
"She was quizzing him on his intentions with various women and generally having very little faith in him. It all became too much and Harry found her a little too demanding.
"Taylor probably engineered the split but Harry held all the cards in the relationship."
