Rowanne Brewer, the sexy 23-year-old blonde now being linked with Donald Trump, is a hometown girl. A graduate of South Lakes High School in Reston, Brewer has hit the current issues of Time, Newsweek and People magazines and is being touted as the woman who is replacing Marla Maples in Donald's affections. Being connected with Trump is good publicity for the former brunet "Star Search" model who was the 1988 Miss Maryland, as part of the Miss U.S.A. contest, in which she won the Miss Photogenic award. As for Brewer's special appeal, Sid Sussman, president of American Pageants, said, "We had to tone her down for the Miss Maryland -- U.S.A. contest because she was so sexy." She also won the Best Body on the Beach contest in Atlantic City, N.J., the same year. Brewer once worked as a bartender at Clyde's and Da Dominico in Tysons Corner and the Dome in Washington. She moved to Maryland after graduating from high school and now lives in Florida.

Brewer did some modeling here through the Erickson Agency, appearing in a Spa Lady ad and making the cover of a Budweiser calendar. She was one of the bright spots of the Erickson Agency's "Great Bodies" poster with her vital statistics: 5-foot-8, 36-23-35 1/2. This is the woman whom Chuck Jones, the publicist for Marla, described angrily as a "bimbo." Tricia Erickson, who has worked with other models who have made lucrative catches -- such as Maryland girl Lesly Brown, who married "Wheel of Fortune" host Pat Sajak -- had some advice for Trump: "Look out, Donald, this girl is no bimbo. If she's smart enough to take advantage of the publicity to promote her own career, I say, 'Go, Rowanne, go.' " Out and About

Dorothy Heyser, the 64-year-old wealthy Dallas socialite who was John Tower's longtime companion, was married for the fourth time last night, and the groom wasn't Tower. Heyser, said to have been a Hollywood starlet who once dated Clark Gable, tied the knot with Robert Goddard, a wealthy Texas business man who reportedly is in oil and ranching. Her wedding to Goddard came as a surprise to friends since she and Tower had been close companions since they first met in January 1986. She was the supportive presence at the former senator's side during the Senate hearings on his failed nomination for defense secretary. When a friend of Tower, Goddard and Heyser was asked if the announcement came as a surprise to Tower, he said the appropriate word was more like "shock," but, he added, "He's now adjusted to it" ...

A New York judge who died earlier this month left the bulk of her substantial estate to the daughter who testified against her in a notorious trial involving former Miss America Bess Myerson. Sukhreet Gabel, daughter of state Supreme Court Justice Hortense Gabel, testified for the prosecution during the 1988 federal trial in which Justice Gabel was accused of granting Myerson's lover favorable treatment in a divorce proceeding.
