Sly and the Family Stallone That former Washingtonian with muscles and money Sylvester Stallone has been seen around Paris lately with blond model Kathy Lyn Davis, but according to his mother, there's no new blond in his future. "He called me from Israel {Wednesday} to tell me I might see something about this girl and to assure me that it's about as serious as me getting pregnant next week."

Stallone's outspoken mother, Jacqueline L. Stallone, who owns and trains the Glow Girls wrestling team, said, "I told him this time go for someone with a brain -- no more of these airheads." As for Stallone's second wife, Brigitte Nielsen, she said, "I think she looks like a female impersonator." And her son's first wife, she added, "had the intelligence of crab grass."

It had been widely advertised for about 10 months that the Spanish tenor would perform, but he has now mysteriously begged off, citing rehearsal obligations at the Metropolitan Opera. Metropolitan officials said Domingo is scheduled to sing the title role in Verdi's "Otello" in New York on Sept. 21, adding that his presence at the Sept. 15 rehearsal was strongly urged, but not essential ... At Arizona State University in Tempe, where Pope John Paul II will celebrate mass on Sept. 14, there is a bit of a problem. The school team's colorful name is Sun Devils. There are cute imps and pitchforks painted in a number of places on the stadium walls. So the little imps will not offend the pontiff, they will be hidden with banners. And instead of referring to the facility by its usual name, Sun Devil Stadium, church officials are calling it ASU Stadium ...
