Louis Walsh makes major mistake within first few minutes of Celebrity Big Brother

Louis Walsh made a hilarious blunder as he entered the Celebrity Big Brother house tonight (4 March).

A whole host of celebs have begun entering the iconic house as the show returned after a five-year hiatus, and excitement for what's in store is sky high among fans.

Louis Walsh was one of the first celebs to enter the house as he joined his X-Factor pal Sharon Osbourne, who entered the house first as a 'celebrity lodger'.

But the former X-Factor star had barely gotten out of the car before he made a major error.

After getting out of his car, the music manager and TV star was interviewed by hosts AJ Odudu and Will Best.

"You're through to the Big Brother house!" Will told him, as a reference to the singing contest he's best known for.

He then asked: "So who are you going to be gravitating towards in there?

"Is it gonna be the boys, the girls, the over 25s or groups?"

Without missing a beat, Louis replied: “Mrs O. I’m with Mrs O!

"She’s gonna protect me."

Yikes.

Will and AJ looked visibly shocked by his answer, as we're normally under the impression celebs don't know who else is heading in as they enter the house.

Trying to style it out, AJ said: "Is she in the house?! She might not be in there!"

Louis then went on: "I heard she went in..."

Will then attempted to salvage things, adding: "Who have you been talking to?!

"It doesn’t matter!"

Safe to say, eagled-eyed fans didn't miss the mistake, with one writing on X: "Someone’s getting sacked from #CBBUK after Louis found out he’s with Sharon."

Another added: "I’m SCREAMING at Louis giving the game away that they all know who’s going in," while a third wrote: "Not Louis letting slip that he knows Sharon has already gone in."

Aside from the iconic X-Factor duo, so far we've had Love Island star Ekin-Su Cülcüloğlu, Corrie's Colson Smith, Ibiza Weekender's David Potts, Levi Roots, Strictly Come Dancing's Nikita Kuzmin, Zeze Millz, Lauren Simon and Kate Middleton's uncle Gary Goldsmith have entered the house.

Fans will be hoping the celebs will shake things up and create some viral moments, but they're up against some tough competition from previous years.

From 'David's dead' to Gemma Collins telling Gillian McKeith to 'f**k off', not to mention Nikki Grahame's iconic rants and Perez Hilton's jaw-dropping return to the house, there's a shed load for this year's lot to live up to.

Bring it on!
