Rob Lowe admitted that he and Demi Moore — who starred alongside him in the 1985 movie St. Elmo's Fire — had a fling while members of the the Brat Pack in the 1980s. "Demi and I briefly," Rob began this week’s episode of Kelly Ripa's Let's Talk Off Camera podcast. "I'm not telling tales out of school—we briefly had a thing." But he said the romance didn't last, with Demi going on to get engaged to their fellow Brat Packer Emilio Estevez in 1985 before calling it quits the following year and ultimately marrying Bruce Willis in 1987. Through it all, Rob insisted that he and Demi have managed to maintain a strong friendship.
