During a link on This Morning, co-host Phillip Schofield was trying to retain an air of mystery but Holly managed to put her foot in it
The bubbly blonde presenter got so excited about the latest stars to be linked to the Channel 5 show she blurted out the answer instead of keeping it secret.
Her co-host Phillip looked totally dismayed at his pal after trying to retain an air of mystery about the news until after the break when showbiz host Ferne McCann would reveal all the details.
"Which Gogglebox stars are allegedly set to enter the Celebrity Big Brother house?" he began before Holly rudely interrupted.
"It's the guys from Brighton! Oh come on... You said 'who are the two guys from Gogglebox?'"
A frustrated Phil laughed as he told his couchmate: "Yes but you're not supposed to say! It wasn't a question for you!"

The duo came back after the break to talk about the rumours Channel 5 bosses were eager to sign up couple Chris Steed and Stephen Webb to join the line-up .
According to reports the popular duo have been offered a big money cheque to ditch the Channel 4 show so they can appear, but that means they may have to say goodbye to Gogglebox.
"The show’s producers are really keen to get them on and would be happy to pay up to £500,000 to see it happen," a source told the Sun newspaper.

"Everyone’s really excited at the prospect because they are so dynamic and they already know they make great TV. They're fan favourites and their dry humour is bound to be hilarious in the house."
This isn't the first time producers have looked to the Channel 4 show for potential housemates. In 2014, they famously recruited George Gilbey, who went on to finish up in fourth place.
