THE Celebrity Big Brother house descended into chaos after a row over beds broke out just hours after the group entered.
When the CBB bedroom doors opened, the stars rushed in to lay claim to the best spots - but two housemates in particular fancied prime real estate.
Real Housewives of Cheshire's Lauren Simon settled herself on the highly sought-after double bed only to be turfed off by X Factor legend Louis Walsh.
The exchange caused sparks to fly.
A source said: “Lauren isn’t used to not getting her own way but when it comes to age and star-power Louis, of course, totally outranks her.
“It was hard for her to form any kind of solid argument as to why he ought to make way for her to enjoy the bigger bed solo over him, but she put up a good fight.

“It was the first sign of tension in the house, just hours after the celebs entered - and suggests none of them will be shy about sharing opinions or holding their own.”
It comes after eagle-eyed viewers spotted Louis' pal Sharon Osbourne making her way to her own special bedroom.
The music icon is CBB’s first ever “house lodger” and will only be a guest for five days after agreeing a special £500k deal.
Sharon was given an early challenge in last night's series opener.

She was tasked with judging the other celebrities and put three of them in the firing line immediately.
Sharon picked Ibiza Weekender's David Potts, TV presenter and Kate Middleton's uncle Gary Goldsmith to be in "the danger zone".
All of them are now at risk of facing the public vote later this week and tonight Sharon will select one of them to automatically face eviction.
Celebrity Big Brother line-up
So who are the 13 stars expected to appear in the Celebrity Big Brother house? The Sun's Jamie Downham takes a look...
Sharon Osbourne - TV legend - who is thought to be on a megabucks deal - said she was doing the show for "a good time not a long time"
Louis Walsh - Irish boyband manager who has never knowingly backed down from a fight. Sure to be a huge presence in the house.
Ekin-Su Cülcüloğlu - We know from Love Island, the Ek-ster is not above throwing about some dramatics to claw her way to the final.
Levi Roots - Reggae Reggae Sauce sauce packs a bit of a kick, but its inventor seems quite mild-mannered. Will that change under pressure?
Fern Britton - The former This Morning star called out Phillip Schofield - don't think she won't do the same to anyone who tangles with her.
Colson Smith - You'll probably know him best as Corrie's Craig Tinker - but prepare to find out he's not much like his character.
David Potts - Ibiza Weekender's breakout star is sure to bring a bit of the party isle to the house... but will people appreciate it?
Gary Goldsmith - Kate Middleton's uncle is a big signing for ITV, but very much an unknown quantity among viewers.
Marisha Wallace - Top Broadway star may fill the brief of 'American who doesn't know what they've let themselves in for'.
Nikita Kuzmin - The Strictly pro is coming onto the show fresh off the show's tour. Poor lad probably just wants a rest.
Zeze Mills - the social media star has a "no holds barred interview style" - which is just what we need in there.
Bradley Riches - The actor played sweet James McEwan in Netflix hit Heartstopper. We'll soon find out what he's really like.
Lauren Simon - She's a Real Housewives of Cheshire star and you don't get on that show by being shy and retiring.
