A source tells ET the wedding will take place Aug. 15 at Twenty Mile House in Northern California, about an hour and twenty minutes from Lake Tahoe.
ET can confirm that Maloney and Schwartz's Vanderpump Rules co-stars Tom Sandoval, Ariana Madix, Jax Taylor and Brittany Cartwright are attending the wedding, which will be filmed for the show.
While Maloney and Schwartz have certainly had their ups and downs on the hit Bravo series, it seems the bride and groom couldn't be more excited for their big day.
ET caught up with Maloney in November, where she gushed about her engagement to the aspiring actor.
"I was very caught off guard. It was very much a surprise, but it was very much Schwartz fashion," she told ET's Brice Sander, before revealing she'd like to keep her last name.
"I've told him we should be very progressive, and [he should] take my last name," she joked. "He doesn't like that idea."
Just last week, she posted a sweet message to her soon-to-be husband on Instagram, as she geared up for their big day.
"Exactly one year ago today he asked me to be his Bubba forever," she wrote, along with a cute PDA pic. "Can't wait [to] marry @twschwa in just over a month!"
Earlier this month, Maloney celebrated her bridal shower, sharing tons of pics from the event with co-stars Scheana Shay, Stassi Schroeder, Madix and Cartwright.
