QVC

QVC personality Toni Brattin's viral on-air slip-up had social media in a frenzy ... but the longtime host tells us the network was nothing but supportive after the unforgettable NSFW live TV moment.

Toni -- who's been in the television business for 30 years -- says she tried to play it off in the moment after mistakenly saying "blow job" instead of "blowout."

She says she immediately realized there was no taking the words back ... telling us she was hoping producers would switch to another camera, which is the reason why she comically froze for a few seconds before continuing the presentation.

Toni says everyone was able to laugh about it once the broadcast ended, revealing to us QVC approached her the following morning and reassured her.
