PK Kemsley says Dorit Kemsley was spending big on luxury brands while their Los Angeles home edged toward financial collapse ... and TMZ has learned he's now asking a judge to force a sale before it's too late. According to court docs, obtained by TMZ, PK says his team looked into how the money was being spent and claims they found out Dorit racked up more than $1 million in luxury spending over the past year or so, including around $995K on high-end designer clothing, handbags, and accessories.
