Miley Cyrus and Liam Hemsworth may be going strong, but it seems like not everyone is happy with it. The former Disney star's friends suggested that she's acting like a very different person when she's around her beau, and they didn't seem to like it.

Miley's friends claimed that the "Wrecking Ball" singer couldn't be herself when she spent her time with "The Hunger Games" actor. "Certain people have complained that she's a different person because of him but she doesn't care," an insider told HollywoodLife.com.

The source went on saying that Miley's metamorphosis might be part of her effort to win Liam back. "Miley's ready to be in a new stage in her life and anyone that cares about her supports that, her family certainly does. She's growing up and that's a good thing," the source continued.

However, the insider alleged that if Miley broke up again with Liam, she might be back to her old habit. "If she and Liam break up it's like she'll go right back to her old habits because he's her motivation for changing," the insider added.

It's hard to deny that since Miley rekindled her romance with Liam she seemed to be more reserved. Earlier this year, another insider claimed that Miley was ready to leave her crazy habit just for the hunky actor. "She's ready to prove to Liam that her crazy party days are over, she wants to be a mom. By the time her mom was 25 she had three kids and Miley's always said she wants to be a young mom too," the insider said.
