Liam Hemsworth Reportedly Moves in with Miley Cyrus

Earlier this week, Liam Hemsworth and Miley Cyrus were spotted strolling down the street.

But a new report says these two are sharing more than a walk these days: they are sharing a roof!

According to The National Enquirer, Miley threatened to move out of her family's Toluca Lake, California home unless her parents allowed her new Australian boyfriend to shack up with them.

"In the end, Billy Ray and Miley's mom, Tish, decided they'd rather have Miley under their roof with Liam than not knowing where she is at night," a family friend told the tabloid, adding that the parents at least insisted on separate bedrooms for the couple.

This actually isn't the first time the Cyrus family has made such an arrangement. In November 2008, Miley's man (and we do mean man!), Justin Gaston, moved in with his young gal pal and her parents.

"Billy Ray believes it's better to keep Miley on a short leash and to monitor her, rather than alienating her and risking a rebellion," the source said. "Whatever happens in her relationship with Liam, her parents want Miley with them for as long as possible."

That may not be for very much longer. Miley is leaving Hannah Montana this year and has made it clear she wants to be treated like an adult.

Her parents should enjoy her company while they can... and cover their ears with a pillow at night.
