Oscar nominee Mickey Rourke‘s beloved Chihuahua, Loki, passed away peacefully Monday night, E! reports.

Actormick_stefa_56099486_600Loki, 18, was famously photographed acompanying with his actor-master at the Venice Film Festival.

Do Hollywood stars look cuter with puppies?

Loki was also thanked — along with all his dogs — by Rourke when he picked up a Golden Globe award in January.

"I’d like to thank all my dogs, the ones who are here and the ones who aren’t here anymore," "The Wrestler" star said, accepting his award. "Sometimes, when a man is alone, that’s all you got is your dog. And they’ve meant the world to me."

His dogs have been with him through high and low times. But he’s definitely on a high now.

Rourke seems poised for his Oscar on Sunday and perhaps even an Independent Spirit Award on Saturday.

Loki would be proud.

As all of us who have lost faithful fur companions can attest, there will be a tremendous sense of loss and deep mourning ahead for Mickey.

Our thoughts and prayers are with the accomplished actor, who will be grieving for his pet, Loki, despite all the awards hoopla this weekend.
