Conan Jokes About 'Illegimate Son'

Conan O'Brien hopped on Twitter on Tuesday (January 14th) to address a recent rumor that he fathered an illegitimate son with an employee at 30 Rockefeller plaza nearly 20 years ago.

A kid in New Jersey is falsely claiming to be my illegitimate son. For the record, I have three children: Neve, Beckett, and @RonanFarrow.

The tweet was a response to a YouTube video posted last week by a guy named Greg Keating who looks exactly like Conan.
