RTE anchorman Aengus Mac Grianna's on-air gaffe has been shown on a top US talk show.
The clip of Aengus applying make-up and fixing his tie while cameras rolled prompted howls of laughter on Jimmy Kimmel Live.
Kimmel jokingly announced Aengus as the winner of the US show's "international edition of excellence in reporting".
Aengus, who fronts RTE's main nightly news, is a hit in the US, with his blooper being reported in the Huffington Post and other high-profile publications.
Kimmel has recently moved to a new time slot, so Aengus was seen by an estimated 3.1m viewers.
