"A kid in New Jersey is falsely claiming to be my illegitimate son," Conan tweeted, referencing a YouTube video uploaded last week by Greg Keating. "For the record, I have three children: Neve, Beckett, and @RonanFarrow."
Conan's less-than-serious response to Keating's claim likely stems from the fact that Keating is probably kidding.
But, then again, maybe he isn't.
He says the idea that Conan might be his dad came to him after years of being told he looks suspiciously like him (so much so that he began calling himself Greg O'Brien).
One day he was snooping around and found "old NBC files in the cabinet upstairs." He told Boston Magazine he isn't "too clear on that time of [his mother's] life [because] she doesn't like to talk about it."
Keating hopes Conan will submit to a blood test so they can settle this matter once and for all.
