Vanderpump Rules star Tom Schwartz revealed that his younger brother Bert is struggling with alcohol addiction.

During a recent episode of the Vanderpump Rules, Schwartz shared  with Lisa Vanderpump that Bert had to be rushed to the hospital from rehab and might have cirrhosis, a serious liver condition caused by prolonged alcohol abuse.

The Stars on Mars actor told that his brother was his "ray of sunshine" until the "dependency on alcohol."

Schwartz also confessed that Bert's situation has made him fearful and prompted him to reflect on his own alcohol consumption habits, which also led him to recognize the need for "moderation" in his drinking behavior.

During the show, a fan asked him when he planned to "slow down on drinking."

 Schwartz, who recently finalized his divorce with Katie Maloney after five years of marriage further added, "I almost always practice moderation. I’ve had a sloppy few."

He has triplet brothers named Robert "Bert," Brandon, and William "Billy."
