Film star Orlando Bloom has pleaded for help to find his and fiancee Katy Perry's dog Mighty, who has gone missing.

Mighty disappeared near the couple's home in Montecito, California.

The poodle is chipped and his collar has a number to call if he is found.

Bloom, 43, is offering a reward for the dog's safe return but the Lord of The Rings star asked fans only to send "real info".

He wrote on Instagram to his 4.1 million followers: "MIGHTY IS MISSING in Montecito California.

"He is chipped and his collar has a number to call - if you take him to your local vet or shelter or police station he can be traced back to me for a reward.

"Please only send REAL INFO - my heart is already broken so please don't add insult to injury."

There were best wishes from at least one of the couple's famous friends.

Danish supermodel Helena Christensen commented on Bloom's Instagram post: "I can't imagine the pain you're going through. Mighty must and will be found."
