While Miley Cyrus and Liam Hemsworth's relationship appears to be stronger than ever, not everyone is happy about it. Her family has reportedly started having second thoughts about the Aussie hunk, though he has been a good influence on her lifestyle.

Words are Miley's family is "worried sick" about her because she's changing so much for him. "Liam has her wrapped around his finger. The two of them are not getting along like they want everyone to believe and he is so wishy-washy," sources tell OK!.

"Her entire family is starting to think that Miley is going to far by changing who she is to fit who Liam wants her to be," the so-called insider spills. "It is a good thing that she has quit using drugs but the fact that she is changing every aspect of herself including how she dresses and how she interacts with her fans is really starting to worry everyone."

The source adds, "You don't change yourself for a man. Everyone knows this." And it doesn't help that they keep postponing their wedding. "They have changed the wedding date like 12 times already," the source reveals.

Miley recently released her new single "Malibu", which is dedicated to her fiance Liam. "I never would've believed you if three years ago you told me/ I'd be here writing this song/ But here I am, next to you/ The sky's more blue in Malibu," she sings in the song.
