Alexa Ray Joel, the daughter of pop singer Billy Joel and supermodel Christie Brinkley, has been released from a Manhattan hospital Sunday, after being rushed there Saturday afternoon for treatment of an overdose of pills.

"She is going to be fine," said Joel, who lives in Sag Harbor, N.Y.

Two sources close to the family said Sunday Joel had taken Traumeel, an antihistamine. Authorities had yet to confirm what medication she had ingested.

Claire Mercuri, Joel's publicist, confirmed Alexa Joel was released from St. Vincent's Hospital in Manhattan a few hours after being admitted. Mercuri declined to comment further.

New York City police said Sunday they are no longer investigating the case and criminal charges are unlikely.
