Miley Cyrus may or may not be tying the knot with Liam Hemsworth anytime soon, but that doesn't mean she doesn't love his siblings or their rugrats.

The onesie and marijuana enthusiast and overenthusiastic twerker is already part of the hunky Aussie clan, being called "Aunt Miley" by Chris and Luke Hemsworth's tots.

Samantha Hemsworth, wife of Liam's oldest brother Luke, told PEOPLE, "She plays with our kids. She loves our kids."

Luke called her "lovely" and affirmed, "She is ['Aunt Miley'] already."

While no one would reveal whether or not there was any domestic strife between Cyrus and her beau, Luke did offer a potentially telling piece of relationship advice: "Never go to bed angry. That's it."

Luke also said that he "won't be" planning Liam's bachelor party, explaining, "I'm sure he'll ask someone who knows him better."

It's also safe to assume that whoever is putting it together will have to run a guest list by Cyrus. We're guessing no one named after a calendar month is going to be invited.
