Jessica Simpson says her "heart is broken" over her missing 5-year-old maltipoo Daisy.

On her Twitter page, she writes: "A coyote took my precious Daisy right in front of our eyes. HORROR! We are searching. Hoping. Please help!"

She also posted posters of the pooch. "Reward offered," they read.

Daisy was a gift given to Simpson, 29, by ex-husband Nick Lachey several years ago. The singer rarely travels without the dog. 

Fans consoled the singer, who was just in Rio de Janeiro shooting her VH1 reality show The Price of Beauty, on Twitter.

"My heart hurts for you," one wrote. "I'm an animal lover and it's like losing a family member."
