WHEN TEEN EGOS CLASH

The increasing; popularity of heartthrob Joey Lawrence, 16, who plays dimwit Joey Russo on NBC's Blossom, is apparently not sitting well with either Mayim Bialik, the 17-year-old star ol the series, or her parents. Sources connected with the show tell us that the Bialiks are so jealous of Lawrence's success—he has a Top 40 single. "Nothin' My Love Can't Fix," and a new album, both out on Impact/MCA—that they have banned his music from being played on the set and have barred Lawrence's reps from bringing journalists there to interview him.

The Bialiks deny all of this, calling the charges "ludicrous."

EAT AND RUN?

When Prego, an Italian restaurant in Manhattan, let it be known recently that Donald Trump still owes $115 on a tab he ran up there last (all for meals and takeout, Trump dismissed the claims in the press by saying he had "never heard" of Prego.

To jog his memory, we faxed him a copy of a $56 American Express receipt, signed by him, for another meal at Prego last September. Okay, says The Donald, so maybe he spoke too soon about never having been there, but his "inclination" now is not to pay the amount still owed. "[Prego] is doing this for publicity," says Trump, no stranger himself to headline-grabbing. "I hale to be ripped off, whether it's for millions of dollars or $115."

Prego's bookkeeper hasn't sent Trump an in- voice for the bill since January. Collecting money from him, she says, "is more trouble? than it's worth.

MAJOR MAZEL TOV
Alas, our name was not on any of the 600 invitations to next Saturday's (March 27) bar mitzvah of Roseanne Arnold's 14-year-old son, Jake. While this frees us from the responsibility of having to buy a gift, it also means we'll miss the specially ordered suede yarmulkes and the ice-sculpted busts of Roseanne and hubby Tom Arnold that will adorn the hors d'oeuvre tables at the reception at Los Angeles' University Synagogue. In fact we hear Roseanne and Tom are so paranoid about such details of Jake's bar mitzvah getting out that they have asked certain people working on the event to sign confidentiality agreements bailing them from talking to the press.

RETREAT TO NEVERLAND
What a relief! The once reclusive Michael Jackson, who has made five major public appearances in the past two months, is not expected to attend next Monday's (March 29) Academy Awards ceremony. A Jackson source assures us that "unless Elizabeth Taylor drags him out, he won't be there." Taylor is Oscar-bound this year to accept the Jean Hersholt Humanitarian Award, which she will share with the late Audrey Hepburn.

TRY A YARD SALE
We should all have such problems. Martin Konigsberg, Woody Allen's 92-year-old father, stores his son's many awards, including his three Oscars, in the New York City apartment he shares with Woody's 84-year-old mother, Nettie. But Konigsberg isn't sure there's room for one more should Allen win a fourth Oscar for his Husbands and Wives screenplay. "In the early days. Wood's parents were very proud of his accomplishments," says a source who talks regularly with Woody's dad. "But over the years the awards have added up, and now it's just clutter."
