Charlie Sheen is lashing out at ex-wife Denise Richards today, calling her, among other things, a "loser whore."
The ugly attack came after Richards took back a Pug named Henry that she had left at Sheen's house. She claims he was neglecting the dog.
Richards is a well-known dog lover and has even appeared on an episode of The Dog Whisperer.
She did not respond to Sheen's vicious tweet except to say that she did not steal his dog.
Meanwhile, it turns out reports that Sheen's upcoming comedy tour completely sold out in just minutes may not be completely true. Deadline.com is now reporting there are still many tickets available being sold for less than face value just to fill the seats.
