Sam Vanderpump has become one of the most talked-about stars on Made in Chelsea. The 29-year-old reality TV star is the nephew of Lisa Vanderpump, the famous Real Housewives of Beverly Hills icon. In 2026, searches for “Sam Vanderpump” have surged dramatically. Fans want updates on his end-stage liver disease diagnosis, his newborn son Marmaduke, and his famous family connections.
Unlike some reality stars who court controversy, Sam has faced a genuine life-or-death battle. He desperately needs a liver transplant to survive. Therefore, this guide covers everything about Sam Vanderpump’s health crisis, his marriage to Alice Yaxley, and his remarkable family background.
Who Is Sam Vanderpump? Famous Family and Parents
Sam Vanderpump is the youngest son of Simone and Mark Vanderpump [citation:4]. He has one older brother named Jack. His father Mark was a businessman and DJ who ran his own agency [citation:4]. Tragically, Mark died in October 2018 at age 59. An inquest ruled his death a suicide, with drug toxicity listed as the cause [citation:4].
Sam’s aunt is Lisa Vanderpump, the iconic reality TV star who rose to fame on The Real Housewives of Beverly Hills. She now stars in her own hit show Vanderpump Rules. She has a reported net worth of £57million [citation:1]. The family also has an unexpected royal connection.
The Prince Andrew Connection
Sam’s parents met in an unusual way. His father was installing sound equipment at Prince Andrew’s home. The royal dog bit him. His mother, who worked as a private chef for the disgraced Prince, bandaged him up [citation:4].
“They went out for dinner and I think they were engaged within a few months,” Sam has previously shared [citation:4]. Despite this connection, Sam does not speak about the royal link too often.
End-Stage Liver Disease Diagnosis
Sam was diagnosed with congenital hepatic fibrosis at just four years old [citation:9]. For 23 years, the condition did not affect his daily life. However, everything changed in December 2024 [citation:9].
He caught the flu, which quickly developed into life-threatening sepsis. Alice called an ambulance that saved his life [citation:3]. Doctors told him that had he been admitted just 24 hours later, it would have been too late [citation:3].
After recovering from sepsis, Sam received devastating news. His condition had developed into irreversible end-stage liver disease [citation:9]. A transplant is his only chance to see his son grow up.
Baby Duke: Son Marmaduke’s Arrival
Sam and Alice welcomed their first child on 9 February 2026 [citation:8]. They named him Marmaduke and plan to call him Duke for short [citation:8]. The name was a favourite of Sam’s late father, Mark. “My dad always wanted to call my brother ‘Duke’ because he believed my brother would one day become Prime Minister, Duke Vanderpump,” Sam explained [citation:8].
The arrival of baby Duke has brought Sam immense joy. However, it has also heightened his fear of dying. “Am I going to see my child?” he asked himself. “That’s terrifying” [citation:10].
The Living Donor Transplant Dilemma
Sam is currently on the liver transplant waiting list. Over 600 people in the UK are waiting for a liver transplant [citation:9]. Family and friends have offered to be living donors. His mother Simone immediately volunteered, but she was ruled out due to her age [citation:9].
Sam initially refused to consider living donors. “The last thing I wanted was to subject a family member or even a friend who’s healthy to the same journey,” he admitted [citation:9]. However, Alice broke down and told him he needed to be there for Duke and her. Her words changed his mind [citation:9].
His brother Jack is now being tested to see if he could donate [citation:2]. His Made in Chelsea co-star Gareth Locke-Locke shares the same blood type and has also offered to be tested [citation:2][citation:9].
Wedding to Alice Yaxley
Despite his health crisis, Sam and Alice chose to prioritise love. They married in a low-key ceremony before Christmas 2025 [citation:10]. The wedding was arranged within just four weeks [citation:10]. Sam had proposed to Alice in March 2025, shortly after his hospitalisation [citation:3].
The engagement ring reportedly cost seven figures [citation:1]. Alice gave birth just weeks after their wedding. The couple has faced immense pressure but remains united.
Channel 4 Documentary: Sam Vanderpump’s Story
A two-part documentary titled “Made in Chelsea: Sam Vanderpump’s Story” aired on E4 in March 2026 [citation:7]. The film follows Sam and Alice as they face the brutal reality of living with a life-threatening disease. It documents his wait for a transplant and his journey as a dad-to-be [citation:7].
The documentary also explores Sam’s emotional struggle with his father’s death. He admitted he couldn’t talk about his father for six years after his passing because the grief was “too raw” [citation:4].
Sam’s Net Worth
Sam Vanderpump is thought to be worth around £1.5 million in total [citation:6]. He has built his wealth through his TV appearances, business ventures, and work as a model. His aunt Lisa has a significantly higher net worth of £57million [citation:1].
