On the September 22nd episode of The Ellen DeGeneres Show, Brooke Shields divulged that she can still fit into the Calvin Klein jeans she wore in the iconic commercial 30 years ago at the age of 15. The actress and former model’s mom, Teri, had kept the jeans since the ’80s and when Shields finally got them back, the 45-year-old mom of two admitted, “They didn’t look pretty, but they fit.” In the ad, Shields suggestively said, “You want to know what comes between me and my Calvins? Nothing.” She told DeGeneres, “That was one of the first times they had sort of smart and provocative television commercials.” Watch the full interview after the jump.
