Just months after a feud tore the famous family apart, The Real Housewives of Beverly Hills star Lisa Vanderpump's brother Mark died of a suspected drug overdose on May 1 at just 59 years old.
And now, in an exclusive interview with RadarOnline.com, the British DJ's fiancée claimed he committed suicide!
"It was for sure suicide," the heartbroken Gemma Walker, 36, told Radar. "I was the last person he spoke to."
The model told Radar she received cryptic messages from her fiance the day before his death.
"He sent me a text message that said he was going to a better place," she said. "The last message he sent me was 'My fingers are getting slower.' I didn't understand it at first. I was calling him and texting him back, and I heard nothing."
U.K. officials told Radar earlier this week that Mark was rushed to a local hospital before he passed away.
"Of course I am devastated. I loved him very much. I am with my family now," said Gemma, who became engaged to Mark after three years of dating.
As Radar previously reported, Mark and Lisa had an explosive fight in a swanky New York restaurant earlier this year. At the time, sources told Radar that he was planning to write an explosive tell-all book about their feud.
But the reality mogul, 57, claimed that the two siblings had reconciled since the fight.
"'He was my only sibling, and I am shocked and saddened by his passing. I am trying to be supportive to his two young sons that he has left behind, and help them get through this tragedy," Lisa, 57, said in a statement.
"We appreciate your consideration in this private and extremely difficult family time."
