LeAnn Rimes Eddie Cibrian nobu children dinner smile singer happy

Looks like LeAnn Rimes is fitting in perfectly as stepmom to Eddie Cibrian's sons, Mason and Jake.

The happy family, all smiling, left Nobu in West Hollywood hand in hand. The young boys are such cuties and they already know how to ham it up for the cameras!

The country singer, sporting cheetah print short shorts and black espadrilles, has never looked more content. You go, girl!
