Miley Cyrus is calling for a little more passion from someone after sending out a series of heartfelt tweets - but she insists the posts were not aimed at fiance Liam Hemsworth.

The singer/actress left followers scratching their heads with a trio of candid tweets on Thursday (13Sep12).

She wrote, "ever feel like you want just... something more. not sure what exactly... passion perhaps?"

Cyrus added, "sometimes i feel like i love everyone more than they love me. hatttte (hate) that feeling."

And she later posted, "Thought of the day: maybe it's not that they love you less, they just love you the most they are capable of loving."

The tweets come days after Cyrus was caught up in an alleged fracas at a Hollywood nightclub.

Police in Los Angeles have launched an investigation after an unnamed man filed a complaint against the 19 year old, claiming she lashed out at him during a squabble between him and her fiance at Beacher's Madhouse, housed in the Roosevelt Hotel, on Sunday morning (09Sep12).

Realising her tweets suggested she might be upset with Hemsworth, Cyrus assured fans "there is not trouble in paradise... just thoughts," and she later offered further reassurances that there's no drama in her love life, adding, "having some quality fiancé time. just what I needed."

Cyrus is no stranger to online drama - she ditched Twitter last year (11) after the media started taking her posts too far and created scandalous stories out of them and the candid shots she put up on the microblogging site.
