The former Star Wars star and author, 56, displayed bizarre behavior while performing aboard the Holland America Eurodam cruise ship in the Caribbean.
In a video obtained by TMZ, the actress is slurring a couple of off-key songs, while her dog goes to the bathroom on stage.
But her rep shoots down reports that she was under the influence, telling PEOPLE in a statement, "There was a medical incident related to Carrie Fisher's bipolar disorder. She went to the hospital briefly to adjust her medication and is feeling much better now."
