SACRAMENTO, Calif. (AP) _ Actress Raquel Welch has been hospitalized, but she instructed hospital officials not to say why.

''Raquel Welch is here and that's the only information I can verify,'' Diana Wilson, a spokeswoman for Sutter Memorial Hospital, said Tuesday.

Wilson, who declined to say when the actress was admitted, said no additional information was being released ''per her (Miss Welch's) request.''

Sylvia Gold, a spokeswoman for the actress, did not immediately respond to a request for information.

Miss Welch, 48, appeared in such movies as ''Fantastic Voyage,'' ''One Million Years B.C.'' and ''Myra Breckinridge'' in the 1960s and early 1970s. More recently, she starred in the NBC made-for-TV movie ''Right to Die.''

LA QUINTA, Calif. (AP) - A desert mansion under construction for TV producer-turned-businessman Merv Griffin was heavily damaged by fire, authorities said.

Tuesday's blaze caused about $1 million in damage to the $1.75 million home, fire officials said. Its cause was not determined.

The house, more than 100 miles east of Los Angeles near Palm Springs, was 80 percent complete, ''and a little more than half of it was destroyed,'' said Riverside County Fire Capt. Brenda Seabert.

Griffin, who has numerous homes, is in the process of building another one atop a mountain in Beverly Hills. In between house building, he is attempting to buy the Resorts International hotel-casino in Atlantic City, N.J., from New York developer Donald Trump.

Griffin, 63, taped his last ''Merv Griffin Show'' in September 1986, ending 24 years as a television talk show host. Later, he created such TV shows as ''Wheel of Fortune'' before selling his TV production company to the Coca- Cola Co. Fortune magazine has estimated his worth at $300 million.

LONDON (AP) - Prince Charles, an outspoken critic of stripped-down modern architecture, will narrate a television documentary he wrote on the subject, the program's producer said.

''The Prince of Wales has done more than anybody to bring architectural issues into the public arena,'' said producer Christopher Martin of the program, ''A Vision of Britain.''

The 70-minute show, part of the British Broadcasting Corp.'s ''Omnibus'' series, is scheduled for broadcast Oct. 28, Martin said.

A Buckingham Palace spokesman, speaking on condition of anonymity, confirmed the report Tuesday.

The 39-year-old heir to the British throne has taken potshots at the modern architecture sprouting up among Great Britain's classical Georgian and Gothic Victorian edifices.

In one speech, he accused modern architects, planners and developers of causing more harm to London's skyline than the German air force did during the World War II blitz.

OMAHA, Neb. (AP) - The daughters of comedian Jack Benny and movie star Gary Cooper say they have fond memories of growing up with their famous fathers.

Joan Benny said Tuesday she told one of her sons, ''I wish you had known him. You could learn one important thing from him: humility. ''

Maria Cooper Janis said the only thing that seemed to set her parents apart from less famous folk was the way they were treated in places like Maxim's, the Paris restaurant.

Ms. Benny and Mrs. Janis, both only children of the legends, opened the 25th season of the Omaha Women's Town Hall lecture series with reminiscences of their youth.

Ms. Benny said she grew up in Beverly Hills, attending public and private schools and ultimately Stanford University before moving to New York to start a career in modeling and acting.

After failing to achieve much success, she said, she returned to California, where rearing four children became her career. Ms. Benny, who is divorced, now lectures on the evolution of comedy.

Mrs. Janis, a graduate of the Chouinard Art Institute in Los Angeles, said she tries to convey her feelings in her art.

ATLANTIC CITY, N.J. (AP) - Perry Como says the ''awful novelty songs'' that his concert audiences still demand have been haunting him since the 1930s, when he sang with Ted Weem's big band.

''Me and Sinatra and all the rest of the singers used to talk about all the crap we had to sing,'' Como said.

Como, 76, said he still winces when performing such million-selling hits as ''Papa Love Mambo'' and ''Don't Let the Stars Get in Your Eyes.''

'''A Hubba-Hubba-Hubba' was another sick one and another gold record,'' said Como, who performs this week at Bally's Grand Hotel and Casino.

''I still do them onstage once in a while because the audience wants it, but I say 'yech' afterwards.''

ROSLYN, N.Y. (AP) - A beaming Nancy Reagan hugged two Korean children she brought to the United States for life-saving heart surgery five years ago, and declared ''they look wonderful'' during a reunion.

Mrs. Reagan took the shy-looking youngsters by the hands Tuesday while visiting other young heart patients at St. Francis Hospital.

''They speak perfect English, too,'' she said.

The children had returned for their annual checkups at St. Francis, where they underwent open heart surgery in 1983. Both received a clean bill of health.

Mrs. Reagan had learned about the children - Lee Kil Woo, then 4, and Ahn Hi Sook, then 7 - through the Rotary Club's Gift of Life program while she was visiting Korea with her husband in November 1983.

She arranged to bring them back on Air Force One, and has since followed their progress. The youngsters were adopted by an American couple four years ago and live in Flagstaff, Ariz.

The Gift of Life program provides expenses for childrens' heart surgery at participating U.S. hospitals.
