Amanda Bynes loses dog Little Angel, Katy Perry posts photo of Kitty Purry

Amanda Bynes has lost her dog Little Angel forever.

The "Easy A" actress took to twitter Tuesday to ask her approximately 54,000 followers for help finding her teacup pomeranian.

"Everyone: I have the worst news to tell you....little angel got out of my house somehow and is LOST," she tweeted, adding " If anyone finds her I BEG you to please contact me thru twitter, I will give a reward. She means the WORLD to me & I can't find her anywhere."

The actress who celebrated her 25th birthday the day before losing her pet said the light brown pup was only four months old and posted the photo above of the pom.

Hours later, Bynes posted on the micro-blogging site that it was a "sad day."

"Little Angel is in heaven now," she wrote. "RIP I love you."

A sad day, indeed.
