Conan O'Brien has spoken out on Twitter about a new video in which a 20-year-old man with a striking resemblance to the talk show host claims to be O'Brien's illegitimate son.

Gregory Keating uploaded his video to YouTube last week, and in it he introduces himself to O'Brien (and the world) and says that he lives in a small New Jersey town 10 miles outside of New York. Keating's red hair even has the same high flip that O'Brien's does.

Keating shows off a baby photo, some signature Conan dance moves and eventually wraps up his two minutes of fame by saying, "I love you ... Dad."

O'Brien's tweet cleverly references Ronan Farrow, the son of Mia Farrow and Woody Allen, who made headlines in October after his own paternity was called into question.

O'Brien, 50, has been married to Liza Powel since 2002.
