The bombshell revelation that Arnold Schwarzenegger fathered a child out-of-wedlock with a housekeeper, behind Maria Shriver's back, is hardly the first scandalous news involving the Kennedy family’s hallowed name.

Here's a few others, just in case you forgot:

On July 19, 1969, on the island of Chappaquiddick, the body of campaign staffer Mary Jo Kopechne was found in Ted Kennedy's car after the politician drove off a bridge. Ted pleaded guilty to leaving the scene of an accident after causing injury, and  the incident was cited by many as the reason he'd never run for president.

Tom Cruise and Katie Holmes walked the red carpet in Beverly Hills, CA. Monday night for the world premiere of the controversial miniseries The Kennedys, and to mark Kate's turn as the iconic First Lady, RadarOnline.com is taking a look at Katie's transformation from Dawson Creek cutie to style icon in her own right.

With her bobbed brown hair, pearls, pill box hat and proper attire, the former Dawnson's Creek star bares a striking resemblance to the one and only Jacqueline Bouvier Kennedy Onassis, who she is playing in the TV miniseries, The Kennedys.

She's a style icon in her own right, but Katie Holmes' transformation into America's most fashion forward First Lady, Jackie O, is nothing short of stunning, and RadarOnline.com has the photos.

What happens when a box office veteran falls in love with a gorgeous actress years his junior?  One of the biggest weddings of the decade!  After a whirlwind romance, engagement and pregnancy, Tom Cruise and Katie Holmes waited 19 months before they made it official at their swanky Italian nuptials at Odescalchi Castle.  It wasn’t surprising that Holmes turned to Tom’s old pal Giorgio Armani to design her a princess-worthy wedding gown, which was embellished in Swarovski crystals.

Kate Middleton may be sporting Princess Diana’s sapphire and diamond engagement ring on her left hand, but it is doubtful she will borrow the former Princess’ wedding gown.  Though Lady Diana Spencer definitely had the most talked about gown of the 1980’s, trading vows with Prince Charles in an enormous pouf-sleeved stunner, which was embellished with about 10,000 pearls, the dress does not seem to mesh with Kate’s far less formal fashion identity.

Park Avenue princess Ivanka Trump and First Daughter Chelsea Clinton both turned to Vera Wang to design their dream gowns. While The Donald's beautiful daughter turned to Grace Kelly for inspiration for her short-sleeved vintage-feeling number, Chelsea opted for a stunning strapless design.
