Schwartz, 34, and Maloney, 30, tied the knot during season five of Lisa Vanderpump's RHOBH spinoff, but RadarOnline.com has learned that they're already out of their honeymoon stage!
"Katie and Tom are on the rocks," an insider revealed to RadarOnline.com.
"Katie is with Stassi Schroeder and the 'Witches of WeHo' 24/7 and isn't focusing on her marriage," the insider explained. "Tom can't stand Katie with the mean girls all the time."

RadarOnline.com previously reported that Maloney teamed up with Schroeder, 29, and Kristen Doute, 34, to take down Scheana Marie, 32, and Lala Kent, 25. Their feud began when Marie and Kent rekindled their friendship, and exploded during an off-camera Eurotrip that excluded Marie.
Doute has come in between Schwartz and Maloney before, as she accused Schwartz of having sex with another girl in Las Vegas during their joint bachelor/bachelorette party in New Orleans.
Maloney has had trust issues with her "flirty" husband since.
Co-star Jax Taylor joked on Twitter that the couple split earlier this month, but Maloney's mom Teri insisted to RadarOnline.com that their relationship "is wonderful."
