Christina Applegate and Brad Pitt went on a brief date in 1989, but the actress left midway through the evening for another man! On Sunday's episode of "Watch What Happens Live," host Andy Cohen and Applegate played a game called "Plead the Fifth" in which guests must answer two out of three questions.

The 43-year-old actress happily answered Cohen's first question: "Cameron Diaz admitted to swimming in the lady pond. Have you ever taken a dip in the lady pond?" "That means gone lesbian for a moment?" she asked. "No, that's not my cup of lady pond," she replied.

The actress pled the fifth too early and declined to answer a question about which one of her many male co-stars were the most well-endowed. "I have to plead the fifth on that one," she replied, flashing her wedding ring at fellow guest, Mark Consuelos, who agreed it was a good call.

Cohen saved his best question for last. "In your files there was much talk of a date with Brad Pitt to the MTV Movie Awards in 1989," Cohen told the actress. "You ditched him for another guy? The question is, who was the guy you ditched Brad Pitt for?"

Applegate looked terrified and was not prepared for the question, "How many fifths do I get," she asked. The "Vacation" star refused to answer the question but did answer some of Cohen's follow-up questions. The guy she ditched Pitt for was not an actor, but he was known to the public. Applegate and the mystery man never ended up dating, and she has seen Pitt since the date. Check out the video bellow to see her full segment on "Watch What Happens Live."
