MONACO'S PRINCE PIERRE: Monaco's Prince Pierre Casiraghi, 24-year-old son of Princess Caroline, was briefly hospitalized following a Manhattan nightclub brawl, the New York Post said.
The grandson of Hollywood actress-turned princess Grace Kelly sustained cuts and bruises on his face when he and his friends got into an altercation with former club owner Adam Hock and his entourage at the Double Seven Saturday, the Post said. The prince was treated at New York Presbyterian/Weill Cornell Medical Center for his injuries and released later Saturday.
Hock, 47, was charged with punching Casiraghi and assaulting three of his friends, whom Hock and his companions insist were being obnoxious by insulting women in Hock's party and drinking from a $500 bottle of vodka on Hock's table.
"I was defending myself and others," the newspaper quoted Hock as saying during his arraignment in Manhattan Criminal Court Sunday. "Why aren't [Casiraghi and his pals] handcuffed?"
Hock was released on his own recognizance and ordered back to court next month, the Post reported.
While the prince's attorney described the incident as "horrifying" and "unprovoked," Hock's lawyer denied his client did anything wrong and called the alleged victims "jealous" "trust-fund babies" and "spoiled brats."
LINDSAY LOHAN: Troubled actress Lindsay Lohan announced via Twitter she is to serve as a guest host on "Saturday Night Live" in New York next month.
Lohan will star in the March 3 episode of the sketch comedy series.
Jack White is to be the musical guest for the night.
Lohan's film credits include "The Parent Trap," "Freaky Friday," "Mean Girls" and "A Prairie Home Companion."
Her once-bright career has been eclipsed in recent years by her addictions to drugs and alcohol, and related legal woes. She started out on the comeback trail last year, appearing in Playboy magazine and booking a role in an upcoming John Gotti bio-picture starring John Travolta.
KATE UPTON: Rep. Fred Upton, R-Mich., says he is proud of his niece, Kate Upton, for landing the 2012 Sports Illustrated swimsuit issue cover.
The 19-year-old model became an overnight sensation when the issue hit newsstands last week.
"She's a great gal," the New York Daily News quoted Fred Upton as telling Fox News.
"I got a lot of my colleagues that are asking if I was adopted," he added. "It's been fun to watch her grow up. ... She's only 19, but we're all proud of Kate."
The Republican legislator chairs the House Committee on Energy and Commerce.
UGGIE: Uggie, the scene-stealing canine star of "The Artist," will not attend the Academy Awards ceremony in Los Angeles, The Weinstein Co. said.
The studio told the BBC the 10-year-old Jack Russell terrier had "not been asked to participate or appear at the Oscars" Sunday.
TWC's statement contradicts rumors claiming Uggie would appear on stage with Academy Awards show host Billy Crystal, the BBC said.
Uggie's trainer from the Animal Savvy animal actor agency in Los Angeles recently announced the animal is being retired from feature films, but will continue to appear in short films and commercials.
Uggie took the stage with his co-stars when "The Artist" won Best Musical or Comedy Feature at the Golden Globe Awards last month.
The French-made, black-and-white valentine to cinema's silent era is nominated for 10 Oscars, including Best Picture.
