Celine Dion appeared yesterday at Caesars Palace in Las Vegas with her whole family -- including 4-month-old fraternal twins Eddy and Nelson -- in tow. Dion is in Vegas to begin rehearsals for her shows at The Colosseum, which kick off March 15.

The 'My Heart Will Go On' singer carried Nelson, slumped in her arms with a grumpy look on his face, while her manager and husband Rene Angelil toted little Eddy, whose outfit perfectly matched his brother's. Dion's dark-haired, light-eyed 9-year-old son Rene-Charles was also in attendance, and stayed close to mom and dad while they posed for photos.

This is one of the first times the public has gotten a solid look at Eddy and Nelson -- who were named after significant figures in the couple's life -- since they were born in October.

With those cute little round faces and matching outfits, would wouldn't want to pinch those baby-Dion cheeks?
