Socialite Jacqueline Kimberly will have to make do on $1,500 a month in temporary support from her estranged husband, Kleenex heir James Kimberly, a judge ruled Thursday. In denying her request for $8,000 a month, the judge called Jacqueline Kimberly's testimony on her needs "outrageous and highly suspect." The socialite's attorney, Jack Ackerman, said the $1,500 would not be enough to maintain her life style. "She can spend $1,500 a week," said Ackerman. "That's just slightly more than he James Kimberly spends each month on his dogs and pets." In a financial affidavit filed in response to his wife's demand for divorce, James Kimberly revealed that he spends $1,000 a month on his pets. The couple married in 1969 when she was 19 and he was 62 . . .
