Miley Cyrus has sparked concern about her relationship after claiming she needs more “passion” in her life.

The 19-year-old star is engaged to The Hunger Games actor Liam Hemsworth.

He popped the question earlier this year, but they have no plans to walk down the aisle any time soon.

Miley has now caused concern by opening up about her feelings on Twitter.

“ever feel like you want just.... something more. not sure what exactly... passion perhaps?” she wrote.

She then admitted she often feels as if she is more caring than most people.

“sometimes i feel like i love everyone more than they love me. hatttte that feeling,” she tweeted. “Thought of the day: maybe it's not that they love you less, they just love you the most they are capable of loving .”

Miley seemingly realised people would start to fear for her relationship after reading her messages. She quickly reassured her fans she was thinking in general terms and it wasn’t a reflection of her romance with Liam, 22.

“& no there is not trouble in paradise.... just thoughts,” she wrote.“having some quality fiancé time. just what I needed.”
