Not only did Ashley Greene's West Hollywood apartment basically burn down on Friday, but three people on the scene were treated for minor injuries and TMZ is reporting that the Twilight starlet lost one of her dogs in the blaze.

Ten fire trucks were dispatched to the 7-story building, and a firefighter on the scene told reporters that the fire started on a sofa. Another firefighter confirmed that one dog was found dead under the actress' bed, but a second dog was removed by Animal Control.

Residents in the building tried to put out the fire with extinguishers, and they told the site that Ashley's brother and assistant "had been going in and out of the condo all morning," so it doesn't sound like Ashley was home at the time.

Ashley's rep added in a statement, "The cause is undetermined."
