Celebrity Big Brother's Sharon Osbourne takes swipe at another A-list celeb as she brands them 'fake'

We're less than a week into the eagerly-awaited return of Celebrity Big Brother, and already, one of the big-name housemates has caused quite a stir...

Former X Factor judge Sharon Osbourne - who'll only be appearing on the show for a short while, due to a heartbreaking reason - has already used her on-screen presence to sensationally slam a number of fellow celebrities.

And by the looks of last night's episode, she isn't prepared to stop dropping bombs anytime soon... take a look:

Since strutting into ITV's infamous Big Brother house on Monday night, the 71-year-old has opened up about some of her most scandalous A-list encounters throughout the years and, let's just say, she did not hold back when it came to certain stars.

On Wednesday night's instalment, the fiery redhead - who is reportedly being paid a staggering £100,000 a day for appearing as a 'celebrity lodger' on the show - began talking about the Hollywood name-droppers she just can't bear.

"When my friends talk about people they know or people they've met, we would always take the mick and say, 'Well if you drop the names, I'll pick them up'," she told pals Louis Walsh and Gary Goldsmith - the uncle of Kate Middleton.

"I'll tell you who does that, James Corden. He does that all the time," she went on, adding that he 'played the LA game' when he left the UK for the States.

"I go to him, 'I really like your shoes', and he goes, 'Yeah, Stella McCartney'. I'm like, I didn't ask you who made them, I just said I like your shoes," she went on.

Her fellow music judge Louis, also 71, then chimed in to jibe, 'Kissing all the right people. Anna Wintour, mwah, mwah', after which Sharon shocked viewers by dropping the C-bomb.

"Oh she loves him, loves him. But who loves Anna Wintour? I think she's the C-word," she admitted.

"Yeah, she is," Louis agreed. "And Ellen DeGeneres?" at which point Sharon did a vomiting gesture at the mention of the name.

And it looks as though Sharon's shock revelations aren't quite over, after The Osbourne's matriarch took aim at another much-loved star during last night's instalment.

Gossiping about global superstar Adele on Thursday evening, she told her co-stars she reckons the singer 'puts on' her entire persona.

"I think she claims the [faux cockney accent], 'Oh, love, oh I'm Adele, I'm so English'," Sharon hit out.

After Gary, 59, began laughing, admitting he's a big fan of the Grammy Award winner, Sharon went on: "It's like, cut the crap, you don't talk like that anymore, just sing, just be true to who you are!

"But she does all this old English, you know?"

Some viewers seem amused by the mother-of-three's outburst, with one penning on social media: "Sharon Osbourne is one of the best housemates we’ve EVER had. Absolutely sensational. #CBBUK"

Others, however, weren't too pleased with Sharon's choice of words: "Sharon took it too far she just called Adele fake?"

"I draw the line at Sharon slagging off at Adele," a second wrote.
