Rob Lowe and Demi Moore , two of the biggest stars to emerge from the so-called Brat Pack of the 1980s, appeared together in the era-defining films About Last Night and St. Elmos Fire. According to Lowe, the pairs on-screen chemistry spilled over into real life.

Appearing on Kelly Ripas Lets Talk Off Camera podcast this week, the 9-1-1: Lone Star actor acknowledged that he and Moore had a short-lived romance.

After joking that a big, big sex orgy took place behind the scenes of St. Elmos Fire, he told Ripa: Demi and I briefly Im not telling tales out of school we briefly had a thing.

Though Lowe didnt specify the exact timeline of his relationship with Moore, he noted it was before she got engaged to another St. Elmos Fire actor, Emilio Estevez .

Look, anytime you put young 20-something men and women together, hookups are inevitable, he quipped. I dont think that has changed.
