COLLINS OFF PRIME TIME

Joan Collins, the Queen of Mean for eight seasons on Dynasty, is no pushover in real life. Collins, 57, was to have starred in the film version of her 1988 novel, Prime Time, but now producers at Ion Pictures say they've abandoned the project because of Collins's "greed and outrageous behavior."

According to co-producer Roy Medawar, Collins had "charged $40,000 worth of clothes to the movie without anyone's approval and made script changes without telling the director [Dimitri Logothetis]." Medawar says Joan also turned down Jacqueline Bisset and Ann-Margret as potential co-stars "because she wanted to be the biggest name in the movie."

Medawar put the budget for Prime Time in the $5 million to $6 million range. "We tried to tell her this wasn't Dynasty or a $20 million movie at Paramount, but she didn't want to listen," he says.

Collins's agent, Irving "Swifty" Lazar, confirms that the project is off but says, "It wasn't Joan's fault. She wasn't greedy. The producers defaulted on her $300,000 salary," a charge Medawar denies. Lazar insists: "They're amateurs, and they never came up with the money."

SCANDAL SELLS...AGAIN

It's the first law of public relations: "Bad publicity is better than no publicity at all." And it happens to be true. Take the case of rocker David Bowie, 43, who is currently out on the American leg of his Sound + Vision concert tour. Recently we reported that ticket sales were not going well (PEOPLE, May 7). But that appears to be changing.

Why the sudden interest in Bowie? Well, according to a source close to the rock star, sales have picked up "considerably" ever since Bowie's ex-wife Angela, 40, said earlier this month on Joan Rivers's syndicated talk show that she had once walked in on Bowie and Mick Jagger in bed together. Both men strongly deny her story.

TIFFANY TO GROW UP

Now that singer Tiffany is 18 years old, she's leaving her teen-queen-in-the-mall image behind. "She's a blossoming adult on the verge of a new image," says her new manager, Dick Scott, who also guides the superhot New Kids on the Block. The new grown-up Tiffany will be showcased in her just completed album, which was produced in Boston by New Kids producer Maurice Starr. Scott says the LP "has a harder edge than anything Tiffany's done in the past."

Tiffany jettisoned her past last year when she terminated an agreement with her former manager and producer, George Tobin. She claimed that the 50 percent of her income Tobin had been taking for his services was excessive. Tobin responded by suing Tiffany and her record label, MCA. A settlement is expected soon.

As to the percentage Scott receives for managing Tiff, he says, "It's the standard 20 percent." And Starr? "Zero percent," says Scott. "He is paid a producer's fee."

MILLER'S TIME

When opportunity came knocking for actress Penelope Ann (Dead-Bang) Miller, she didn't hesitate. She answered the door. We hear that Miller, 26, was all but signed to play the second female lead in The Marrying Man, starring Alec Baldwin and Kim Basinger, when suddenly her agent called with the news that she had been tapped to play the female lead opposite Arnold Schwarzenegger in Kindergarten Cop. It took Miller all of two seconds to make up her mind. Goodbye, Alec and Kim. Hello, Arnold.
