Many fans love Miley Cyrus' unfiltered self-expression on her Twitter account, but her fiancé Liam Hemsworth isn't one of them.

Hemsworth is reportedly not happy with a series of "unhappy" tweets that Cyrus wrote, and he told her he wants her to delete her Twitter account completely, according to Hollywood Life.

The tweets in question came on Sept. 13, when Cyrus wrote a series of posts about love and being unhappy. The posts included: "ever feel like you want just.... something more. not sure what exactly... passion perhaps?" followed by "sometimes i feel like i love everyone more than they love me. hatttte that feeling," and finally "Thought of the day: maybe it's not that they love you less, they just love you the most they are capable of loving."

Hemsworth felt the tweets were directed at him and his relationship with Cyrus, and he told her he doesn't want her using Twitter at all.

"Miley's tweet was such a huge insult to Liam. She tried to pass it off like it had nothing to do with him, but it totally affected him, no matter what she tries to say," an insider said. "She was trying to get his attention, but she just ended up making him pull away from her more. He thinks she's acting like an immature schoolgirl, and he wants her to get off Twitter completely."

Cyrus deleted her Twitter account once before in 2009, a decision she attributed to Hemsworth.

"FYI Liam doesn't have a Twitter and he wants ME to delete mine with good reason," Cyrus tweeted at the time. "It wasn't because my friend told me to. I stopped living for moments and started living for people."

Cyrus' next professional endeavor is a guest spot on "Two and a Half Men." The show's executive producer Jim Patterson praised her work on the show.

"We were so excited to get Miley. If it works out, it's going to be great. She's on for two episodes right now and if things turn out well and she has fun, we'd love to have her back. ... We think it's going to be a great dynamic," Patternson said.
