FOX News host Sean Hannity has been caught puffing away on a vape oblivious to the fact that his show was back live on the air.
The prime-time political commentator was caught off guard as the show, Hannity, came back from a commercial.
During the hilarious gaffe, Hannity can be seen staring down, apparently reading something, with his glasses skew-whiff as he puffed away on his vape before letting out a plume of mist.
For several seconds he seems to be aware, before quickly tossing his vape and looking around in an anxious way.
Realizing his blunder, he finally offered up an "uh-oh".
As Hannity handed over to Laura Ingraham, she posed with a water glass in her hand, jokingly prodding her colleague.
She said: "Oh wait, am I on camera right now?
"It happens to the best of us, Hannity" she continued. "I mean, those little moments are cute. Those are in the forever reel of the real Hannity. We wanna know you!"
"Enjoy it, everybody, at my expense," Hannity said before signing off.

Hannity later said he expected to be mocked.
He said:"I have a good sense of humor, I can take it."
