She is the aristocratic, singer who won fame as the runner up on the first series TV talent show The Voice.
Now Bo Bruce is locked in a discordant row with her brother Thomas, Viscount Savernake, over the future of their late mother’s £2million home.
They are the children David Brudenell Bruce, Earl Cardigan and Rosamond Winkley, Cookbook Writer, Countess Cardigan who died at 63 in 2012.
Bo Bruce, 36, wants her brother to be removed as executor of her estate so that her house can be sold and she gets her money
She left her estate to her children in equal shares. This includes Leigh Hill House on the Savernake Estate in Wiltshire.
But the High Court heard that the inheritance has still not been shared between them due to a row over £450,000 allegedly owed by Miss Bruce to her brother.
Miss Bruce, 36 years old, is asking to have her brother removed from the estate executor role so that she can sell her house and get her money.
She admits owing him cash but claims it is ‘significantly less’ than he says.

Her brother, 39, is fighting her to get him out. He says that no sale can be made until the amount she owes is determined by a court.
Barrister Steve Ball, for Miss Bruce – known formally as Lady Catherine Brudenell-Bruce – claims it is not legitimate for her brother to refuse to discharge his duties as executor pending the resolution of the row.
Mr Ball added: ‘It is also not irrelevant that the claimant is in parlous financial circumstances, whereas the defendant is an extremely wealthy man.’

In a statement, Miss Bruce, who married her musician husband Henry Binns in 2016, said she doesn’t have to repay him until she gets her inheritance.
She said: ‘I admit that I borrowed money from him on the understanding that I would be able to repay it when the money from the house came to me…’
Harry Martin, the Viscount, argued that it was unnecessary to remove him as executor. He can still buy her out once the debt is quantified.
Deputy Master John Linwood, the judge, stated that both issues would be decided in early 2022.
