Liam Hemsworth is once again engaged to on-and-off-and-on again girlfriend Miley Cyrus, but not everyone in his family is on board with the relationship.

According to a new report, the actor's older brother Chris Hemsworth wants the 26-year-old to break up with his eccentric fiancée before she has a chance to hurt him.

“[Miley]'s dropping all these hints that she’s not marriage material, but [Liam]'s not catching on at all,” an insider tells NW magazine. “While Miley may love [Liam], if they don’t get on the same page soon, it’ll only end in heartbreak for him.”

The report comes just days after the singer admitted that she doesn't like her engagement bling from the Aussie, and only wears it to appease him.

Despite her diss, the couple made a rare public appearance over the weekend, smiling for a goofy selfie at a friend's art show.
