The reason for the party was to celebrate the North American premiere of the new Jaguar XJL Ultimate. But, despite numerous bunnies hopping around the luxury flagship, it was an ancient relative that snatched the limelight. Mad Men protagonist Don Draper summarised the starring 1963 E-type perfectly in an earlier episode of the retrospective series: “A man getting out of a Jaguar needs a cold shower…”

Hendricks – who plays feisty Joan Holloway in the show – was one of the star guests at the party, and posed for photographs beside her curvaceous co-star. She said of the XJL Ultimate “It's a car you don’t want to get out of – you’ll never want to call shotgun in that car.”
