She may be accustomed to a millionaire lifestyle, but Lilly Becker tucked into a bargain bacon butty from a mobile van on Clapham Common, London on Wednesday. 

The model, 46, who has an estimated £4.1m net worth, couldn't resist treating herself to a greasy breakfast bap while on a dog walk. 

Lilly went for a dressed down look, donning a longline padded jacket and shielded her face with a black baseball cap. 

Her outing comes after her estranged husband Boris, who squandered his £127m fortune through divorce battles and bad investments, issued a marriage warning to Prince Harry in a new interview after his time inside two 'brutal' jails. 

Lilly, who split from the three-time Wimbledon winner in 2018, tied her long brunette hair back and sipped on a hot drink. 

She completed her look with a warm turtle neck jumper, black trousers and a pair of lace-up boots. 

Her outing comes just days after shamed tennis legend Boris told of his time inside two 'brutal' jails - but failed to take responsibility for the bankruptcy fraud that put him there. 

Boris, convicted of hiding assets worth £2.5million, blamed his advisers and even criticised jurors for being too young to understand his case. 

The twice-married sportsman, 55, also offered a startling warning to Prince Harry: ‘Don’t forget where you come from, because you may have to go back there. And marriages don’t always last forever, last time I checked.’ 

Boris was jailed for two-and-a-half years last April after being found guilty of four charges under the Insolvency Act. 

The first part of his sentence was served at London’s notorious HMP Wandsworth, which Becker described as ‘a s***hole’. 

‘It’s a dangerous place. After the first week, I realised that this is survival, and if I spend any time looking back, I’m losing,’ he told the Financial Times. 

‘I need all my energy to survive every single day. The moment they come with the keys – you hear it, it’s a noise you never forget.’ 

Becker taught maths and English to other inmates, allowing him to spend five hours a day out of his cell, which he liked because ‘inside the cell, you die’. 

He was later transferred to Huntercombe Prison in Nuffield, Oxfordshire, where he was ’surrounded by murderers, drug dealers, people smugglers’. 

The German recalled: ‘At first, you’re scared, because this guy killed two people with his hands, he’s already doing 18 years. Imagine! He becomes your buddy.’ 

He added: ‘The British justice system is brutal.’ Becker was backed by famous friends while he was inside. Liverpool manager Jurgen Klopp wanted to visit but was blocked because the prison feared for his safety. 

World No.1 tennis player Novak Djokovic gave Becker’s girlfriend Lilian de Carvalho Monteiro free tickets to his matches. 

His longtime German rival Michael Stich even wrote him a long letter. Becker was declared bankrupt in 2017 but hid £2.5million of assets, including a £1million house in Germany, to avoid paying his debts. 

When he was sentenced at London’s Southwark Crown Court last year, Judge Deborah Taylor said he had shown ‘no remorse [and] no humility’. 

In his FT interview, Becker still refused to take responsibility for his crimes, saying he wouldn’t have been dealt with as harshly ’if my name was Peter Smith and I didn’t win Wimbledon at 17’.
