Carrie Fisher is feeling better after a brief trip to the hospital last week.

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.”
