Might be a bad time to joke about the paternity of Ava Witherspoon — as it's been recently reported that exes Reese Witherspoon and Ryan Phillippe have been arguing over their children!
But clearly, David Letterman wasn't aware of that, so he went for the jugular while conducting an interview with the star on May 6 — and alluded to the fact that he is the actual father of Reese and Ryan's 15-year-old daughter.

During the segment, the 39-year-old actress mentions that Ava was born the first year she ever appeared on Letterman's talk show, to which the 68-year-old replied, "Well, that's an interesting coincidence."
While the audience got the joke right away, it took Reese a minute to pick up on the jab. She later admitted she was having a "blonde moment."
