Twilight star Ashley Greene has adopted two new puppies, three months after one of her beloved dogs died in a fire at her California condo.

The actress, her brother and a male friend escaped unhurt from the Los Angeles property, but one of the star's two dogs died of its injuries.

Greene put her grief behind her on Thursday when she picked up two puppies at Los Angeles' Spot Rescue centre, and she shared a photo of her new pets on her page, writing, "Today felt like a great day to rescue a puppy... Or two! I couldn't take a brother without his sister!"

The actress has called one of the pooches Ralph, but has yet to find a name for the other dog.
