Heard about the new Sonny and Cher dolls? Wind them up and they break apart. Well, not exactly, but starting in May, kids who are bored with their Barbies and Kens will have pint-sized versions of the TV couple to cuddle. That's when Mego International, makers of Batman, Robin and Star Trek dolls, will launch a $1 million ad campaign to market 12 1/2-in. versions of Sonny and Cher to the moppet set. The Sonny doll will come with a twelve-piece wardrobe (including a sparkling silver lame jumpsuit), while the little Cher will have 32 costumes modeled after the tall one's own Bob Mackie creations. The Cher doll "looks just like me," says the singer happily, noting that her look-alike will come complete with the notorious navel and knee-length hair.

First Jacqueline Onassis abandoned the leisure class by taking a job with Viking Press. Now the drive for full employment has been joined by her younger sister, Lee Radziwill, 42, who has just launched her own New York decorating business. Among her first clients: Americana Hotels, which has asked her to redesign some hotel suites in Palm Springs, Mexico and Florida. Says Lee, a former fashion assistant at Vogue and Harper's Bazaar, explaining her innovative touch: "I like to create the unexpected.

If it's New York, I like to make a bedroom into a greenhouse. If it's London, I like to do something exotic so you don't notice the climate." Her credentials? "I've decorated all the homes I've lived in. And family and friends have always asked for my advice."

For all his skills as a serious dramatist, Harold Pinter, 45, seems to have patterned his private life after a daytime soap opera. Last summer the British author of The Homecoming separated from his wife of 19 years, Actress Vivien Merchant, 46, and took up housekeeping with Lady Antonia Fraser, 43, a whirling dervish of London society, a biographer (Mary Queen of Scots) and mother of six. Tory M.P. Hugh Fraser kept discreetly quiet about his wife's affair, but Merchant sued Pinter for divorce, and the new lovemates quickly assumed a low public profile. Lately, however, those profiles have ventured back into the open. Earlier this month Fraser and Pinter appeared together at the London Evening Standard's annual drama-award lunch, and more recently they ran into photographers at Heathrow Airport. As for Actress Merchant, the spurned spouse continues to live in the London house she once shared with Pinter, having long since withdrawn her divorce petition. Says she: "I am quite happy with life and intend to stay on here and find as much work as possible." Now in Act III...

She was a teen-ager looking for a job when Comedian George Burns signed her up for his Las Vegas night club act back in 1960. But Ann-Margret developed fast. After opening some eyes with her singing and dancing, she left Las Vegas after an eleven-day run and set out to become an actress. Last week the pair met again at Burns' Beverly Hills home to toast their most recent successes: George's Academy Award nomination as Best Supporting Actor for his role in The Sunshine Boys, Ann-Margret's as Best Actress for her part in Tommy. "You owe me six weeks' pay at $1,100 a week," insisted Burns, now 80, referring to AM's broken contract. Then accepting three quick smooches from his ex-protegee, now 34, generous George reconsidered. "The kisses," he smiled, "cancel the debt."

In one of her final London performances in 1969, Judy Garland faltered so badly that some members of the audience pelted her with bread rolls. Last week, when Singer Lorna Luft, 23, Judy's daughter and Actress Liza Minnelli's half sister, came to play the London Palladium, it was the critics who did the bombarding. The London Times found her "a not particularly talented performer who tries hard enough but against impossible odds." What she lacks, said the Guardian, "is that bruised-by-life quality you find in most top female vocalists" --a failing that the British critics seemed anxious to remedy. Lorna's own view of her performance: "It went better than I ever dreamed."

He hasn't got the symmetry of Marilyn Monroe or even a Campbell's soup can, but no matter. Willy Brandt, 62, former Chancellor of West Germany and 1971 winner of the Nobel Peace Prize, put on a smile and a pin-stripe suit to pose for Pop Artist Andy Warhol in a Bonn art gallery. Brandt stood patiently for half an hour as Warhol clicked off more than two dozen Polaroid pictures, to be used later to manufacture the politician's portrait. Though Andy will collect a commission for the finished work, which will be auctioned off for the benefit of UNICEF, he insisted that money was not his motivation. Said the artist: "He is, after all, an outstanding man in history, and this was incentive enough."

Hemingway should have had it so good. Former Domestic Affairs Chief John Ehrlichman, who received a $50,000 advance from Simon & Schuster for his first novel, has now peddled film rights to the book to Paramount Pictures. His price: an estimated $75,000. Titled The Company and due in the stores by May, it is about a U.S. President who dabbles in domestic spying, then faces blackmail by the CIA. "If I stick to a routine and don't get too loose, I can write 15 to 25 pages a day," says Ehrlichman. Now appealing his 1975 conviction for Watergate-related crimes, he has already started work on a second book, which he describes as another "purely fictional novel about Washington, D.C." So far, no nibbles from Hollywood.

It was a performance fit for the Queen of Kitsch. With a yellow Rolls-Royce as her carriage and the Harvard marching band for footmen, Singer Bette Midler trouped into Cambridge,

Mass., last week to collect her Woman of the Year award from Hasty Pudding, the university's 181-year-old theatrical club. "I've showered, shaved and F.D.S.ed myself into a stupor," announced Midler, who happily accepted a gold brassiere from club officials and a third-row seat for the annual Hasty Pudding drag musical. Proclaiming the presentation "the most tasteful event with which my name has ever been associated," the Divine Miss M then offered some entertainment of her own: a song and dance number that ended with a skirt-lifting spin to reveal her derriere.

"It took a few phone calls," allowed Jazz Pianist Dave Brubeck, 55, describing his efforts to lure some old chums back for a series of concerts. The calls, of course, went to Alto Saxman Paul Desmond, Drummer Joe Morello and Bass Player Gene Wright, all of whom agreed to join the maestro on a 25-city silver-anniversary tour of the old Dave Brubeck Quartet. The four, who set white bucks a-tapping in the '50s and '60s with hits like Take Five and Blue Rondo a la Turk, have apparently lost none of their appeal since they disbanded more than eight years ago. "We work better than we used to," asserted Papa Dave. "We're older and wiser."
