Drew Barrymore, the precocious actress whose appearance six years ago in "E.T.: The Extra-Terrestrial" tabbed her as one of the brightest child stars since Elizabeth Taylor, has been released from a rehabilitation center following treatment for a drinking problem, her publicist said.George Freeman of P/M/K Inc., said Thursday that Barrymore, 13, was released "a couple of days ago" but would not identify the center or comment on the young actress's situation except to say, "I know she's looking forward to getting back to work. . . . She is in good health and great spirits."

Barrymore, the granddaughter of John Barrymore Sr., and the grand-niece of Oscar-winning actors Ethel and Lionel Barrymore, is about to begin work in "Getting Straight," a CBS Schoolbreak Special with Tatum O'Neal that is scheduled for broadcast in late March.

Barrymore, who played Gertie in Steven Spielberg's "E.T.," started her career before she was a year old, starring in a dog food commercial. Her first feature film was "Altered States," in which she played William Hurt's daughter.

Barrymore is the daughter of former actor John Drew Barrymore, a reclusive poet with a history of drug arrests, and his third wife, writer-actress Ildiko Jaid, with whom she lives.
