and her mum Sharon delighted their fans as they filmed a lighthearted video for Omaze.
The TV star, 41, was recently forced to defend her body against 'cruel trolls' who 'dehumanised her' following her appearance at the this month.
Ignoring all the hate, Kelly joined her mother in filming a promotional video for Omaze, which is giving away a £5million mansion in a prize draw.
It is part of Kelly and Sharon's mission to raise £4.5million for 's charity, Centrepoint.
Sharon and Kelly took viewers back to The Osbournes Show days as they filmed a hilarious video of them bickering while trying to film advert.
'Oh for f*** sake mum', Kelly shouted as Sharon could be heard screaming her name in the background.
Kelly continued: 'Hello, I am Kelly Osbourne and I am very excited to be teaming up with Centrepoint and Omaze to offer you this picturesque house in the Lake District...'
'Kelly! Kelly! Where's the dogs? There you are, have you seen the dogs? What are you doing?', Sharon interrupted.
'No mum. I'm filming for Omaze', Kelly said.
Sharon interjected: 'Did you tell them about the house?'
'I'm trying to tell them now...', Kelly said.
'Well, you could win this house and it's worth £5 million and just be entering you'll be supporting Centrepoint'.
'Don't forget to...', Sharon said.

Kelly insisted: 'Okay mum that's it, you've got to go.'
'Rude!, Sharon remarked.
Fans complimented Kelly on her new blonde locks while also commenting on the sweet relationship she shares with her mum.
People wrote: 'Love the hair like this',
'I love Sharon and Kelly!! ❤️ They are beautiful and funny like Ozzy!! Made my morning!',
'Love this! Kelly and Sharon are icons!', 'Sharon and Kelly you look fabulous', 'Hahaha i love this. Very Osborne behaviour',
'Kelly and Sharon thank you so much. You are doing such a wonderful thing. We love you both so much. Thank you again with all my heart. ❤️'
Earlier this month, Kelly hit out at 'cruel trolls' who 'dehumanised her' following her appearance at the Brit Awards in Manchester.
The daughter of the late Ozzy Osbourne attended the ceremony to collect a posthumous Lifetime Achievement for her father.
But as well as celebrating Ozzy's life during the evening, Kelly also was seemingly subject to negative comments about her appearance.
Speaking on the backlash last week, Kelly said: 'There is a special kind of cruelty in harming someone who is clearly going through something.
'Kicking me while I'm down, doubting my pain, spreading my struggles as gossip, and turning your back when I need support and love most.'
She continued: 'None of it proves strength, it only reveals a profound absence of character. I'm currently going through the hardest time of my life. I should not even have to defend myself. But I won't sit here and allow myself to be dehumanised in such a way.'
Her attendance at a variety of public events over recent months has prompted genuine concern for her health and wellbeing, notably during a front row appearance at London Fashion Week on Sunday.
The singer and TV personality, who denies using weight loss jabs, looked considerably slimmer while attending Ascot Millinery Collective's latest catwalk presentation at Mayfair's Claridge's.
She has since called out her online abusers for subjecting her to a torrent of vile comments, among them an unsavoury remark about her late father, Ozzy, who passed away last July.
Over the years, the British TV personality has been open about her insecurities around weight, which dates back to her teen years while starring in her family's reality show, The Osbournes.
Kelly and Sharon will also relive the family's screwball lives on to raise the £4.5million for Centrepoint.
Kelly, 41, revealed: 'I said I'd only do this if the charity side was really meaningful. I wanted Omaze to match the value of the house and they pretty much have.
'I think William will make an amazing King and I really hope he's pleased with the donation. That amount will completely change the face of the charity.'
It will be the biggest donation received by Centrepoint, whose shelters for the in were first shown to William as a child by his mother Diana.
The advert features Sharon, 73, and Kelly flicking through photo albums from their chaotic lives with Ozzy and Kelly's brother Jack.
They tour the Georgian-style Omaze house and scenes at their own Georgian-style £15million home in Jordans, Buckinghamshire. Black Sabbath frontman Ozzy, 76, is buried in the garden there after his death last summer.

Kelly, who has drawn concern over her recent weight loss, described Charles as 'so kind' for writing and said Sharon kept the letter on her bedside table.
She said she was finding charity work 'really fulfilling' in the aftermath of her father's death.
Omaze has raised more than £100million for charities since 2020, guaranteeing a minimum £1million per house draw.
Previous celebrities featuring in the Omaze prize draw have included Benedict Cumberbatch and Olivia Colman.
Founded in 1969, Centrepoint supports thousands of vulnerable young people every year. Its CEO Seyi Obakin said: 'Kelly and Sharon's generosity, together with their commitment to ending youth homelessness, has made possible a truly inspiring campaign.'
