The Vanderpump Rules star released a statement to The Daily Mail in which she said her brother's death "has come as a shock to us all."

"My brother and I had connected the day before this tragedy and I was completely unprepared for this," she said. "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," she continued. "We appreciate your consideration in this private and extremely difficult family time."

The 57-year-old reality star has been largely silent on social media following her loss, with her last post on Instagram having been shared the day Mark died.
