World famous supermodel Jessica Simpson and husband Eric Johnson picked their Halloween costumes and went for the characters from the 1983 movie National Lampoon's Vacation, and shared the results on Instagram on Sunday, November 1.

National Lampoon's Vacation, sometimes referred to as Vacation, is a 1983 American comedy film directed by Harold Ramis and starring Chevy Chase, Beverly D'Angelo, Randy Quaid, Dana Barron, and Christie Brinkley.

Jessica did her best impersonation of Christie Brinkley, who made an appearance in the film as the sexy girl driving a red Ferrari.

Christie Brinkley took to Twitter on Sunday, to praise Jessica Simpson's Halloween costume this year, a send-up of Brinkley’s bombshell role in the 1983 classic comedy National Lampoon's Vacation.

The 35-year-old certainly had the look in an oversized white shirt worn as a dress, with a matching belt cinching in her tiny waist.

Jessica showed off her slender legs in the costume, and also wore a pair of sky high white platform heels.

The singer turned fashion designer had mastered the comprehensive '80s hair and sported bright red lipstick, with a beer in hand.

Her blonde hair was teased to look like Brinkley's and she showed off her shapely legs in sky-high heels.

Her hubby, meanwhile, was a dead ringer for the Griswold patriarch in dark jeans, a purple polo, and a khaki Members Only jacket.

The 36-year-old former NFL pro sported Griswold's red glasses and side-parted hairdo.

The famous couple appeared to be at a party in someone's garden, and another costumed guest could be seen in the background.

On Saturday, Jessica also shared a photo of her three-year-old daughter Maxwell Drew Johnson's black and pink cat make-up for the holiday.

Jessica and Eric, who celebrated their first wedding anniversary on July, are also parents to two-year-old son Ace Knute Johnson.
