Katie Maloney and Tom Schwartz are engaged.

When Is 'Vanderpump Rules' Star Katie Maloney Getting Married?

Over the summer, amid production on Vanderpump Rules season four, Schwartz got down on one knee after months of not-so-subtle hints from his longtime girlfriend, Maloney, who was ready to take the next step toward their future.

"I think at one point I said it was like an epiphany, like a eureka moment, but that's not entirely true because there's so many different things that led up to that moment," Sandoval told Wetpaint of his proposal, which will be seen on Monday's Vanderpump Rules.

As for Maloney's season three statement about giving Schwartz a six-month deadline to propose, Schwartz said, "I don't think the ultimatum was an effective strategy, but I will say this--it did light a fire under my a**."

"It was like a wake-up call to realize that I honestly could lose Katie," he explained. "We have such a beautiful thing, I didn't want to lose it, so I started fighting for it."

Following Schwartz's July 7 proposal, Maloney spoke to Us Weekly about her wedding plans, and said she and her fiance hadn't yet set a date.

"We haven't begun much planning or set a date, but I have been planning for this since I was a little girl," she explained.
