Blake Shelton designs special pet necklace for Miranda Lambert

Country star Blake Shelton has designed a very special gold necklace for his wife Miranda Lambert's Christmas gift complete with charms for each one of their dogs.

Animal-lover Lambert is known for taking in rescue pooches and her husband has found the perfect way for the singer to keep the pets close to her heart.

A source tells In Touch Weekly magazine, "(Shelton) designed a $20,000 gold necklace with 20 charms on it, engraved with the names of her dogs.

"It's the most thoughtful gift. He designed it for her, and laughed he hoped it wasn't too heavy because she has so many pets."
