A well-known Irish newsreader was left red-faced after being caught fixing herself on live tv.

Keelin Shanley is the latest RTÉ front woman to be left mortified when she wasn't quite camera ready during a recent Six One News output.

The broadcast was finishing up a political segment on the Sinn Féin Ard Fheis with Mary Lou McDonald when the camera shot to Shaleny's direction, catching her off guard.

The Dublin native was seen dusting her shoulders off, and then proceeded to pull a rather hilarious shocked facial expression.
