Ok, I don't think this is really all that bizarre, she was a surprise guest, brought her dog for fun - was relaxed and I think this is being blown way out of proportion. I think this is a case of bad journalism and their version of the story is below the video. What do you think? 

TMZ reports that actress Carrie Fisher was hospitalized last week following a bizarre appearance onboard a cruise ship. Video shows Carrie, who was a “surprise” celebrity guest on the Caribbean cruise, slurring through a couple of songs, while her dog relieves himself on stage. Reports claimed that Carrie, a recovering drug addict, was wasted but her rep insists her breakdown was caused by Carrie’s bipolar disorder. "There was a medical incident related to Carrie Fisher’s bipolar disorder,” said her rep. “She went to the hospital briefly to adjust her medication and is feeling much better now."
