Stephanie Pratt has launched a fierce public attack against her brother, reality TV star Spencer Pratt, following his announcement to run for Mayor of Los Angeles. In a series of posts on X, she strongly criticized his candidacy.

"Spencer has done great work for the Palisades. But LA does not need another unqualified and inexperienced mayor," Stephanie declared. "A vote for him is a vote for stupidity." She accused him of running merely to stay famous and promote his memoir.

Responding to critics, Stephanie revealed past trauma, stating, "he beat me up when I was 18 & put me in the hospital. So no, he doesn't belong in the government." She also made serious allegations about his past, including drug use and an arrest in Costa Rica for illegal firearms.

Stephanie firmly sided with Lauren Conrad in their long-standing feud, stating she will "always side with the vulnerable who need help, not the people inflicting pain on others."

Spencer Pratt announced his campaign in early 2026, arguing the Los Angeles system is "fundamentally broken" and positioning his run as a mission for change.
