Miley Cyrus Introduces Her Mom to Liam Hemsworth's Parents

Miley Cyrus and Liam Hemsworth are taking a major step in their impending marriage ... by bringing out their soon-to-be in-laws for dinner.

Miley and her mom, Tish, met up Saturday night with Liam and his folks, Leonie and Craig, for a fishy meal at Nobu in Malibu.

Looks like it went better than when the Fockers met the Byrneses.
