In July, amid filming on season four, Schwartz proposed to Katie Maloney after several years of dating. The moment was a long time coming for Maloney, who had expressed interest in getting engaged quite a few times throughout season three.

The fourth season of Vanderpump Rules will also include several other notable events, including the arrest of Jax Taylor, the return of Stassi Schroeder and the introduction of new girl Lala Kent.

“This season is really intense. The stakes are so high,” Lisa Vanderpump told Bravo's The Daily Dish earlier this month. "It’s a show where their shenanigans get carried away and they get carried away with themselves. Relationships get very intense this season; it’s an incredibly incestuous group. We have so many incredibly diverse characters. It’s tricky."

For more of Tom Schwartz and the rest of the cast, tune into Vanderpump Rules season four, when it premieres on Bravo on Monday, Nov. 2, at 9 p.m., and check out the trailer below.
