Celine Dion's Kids Get BIG -- See Them Now! (15 PHOTOS)

Celine Dion and her children tend to fly under the radar -- so when they popped up for a photo shoot in Las Vegas this weekend, we were surprised to see how big they've all gotten!

Celine, husband Rene Angelil, 10-year-old son Rene-Charles and 1-year-old twins Nelson and Eddy were photographed alongside the title characters from "Beauty and the Beast" this weekend backstage at The Colosseum in Caesars Palace, Las Vegas.

The family posed with the duo to mark the movie, which Celine sang the theme song to, being released in 3D this Friday.

Aren't they an adorable family? Check out more celeb kids in the gallery above.
