Katie Maloney and Tom Schwartz's happy marriage is a blatant fakery, Breaking Celebrity News can exclusively reveal!

"Yes, they are together but their relationship has definitely been riddled with issues," an insider told Breaking Celebrity News. "Katie doesn't really trust Tom. Tom is a super flirt and he flirts with other women right in front of her."

Schwartz, 34, and Maloney, 30, frequently argued over her trust issues on Vanderpump Rules — and their fight exploded at their joint bachelor/bachelorette party in New Orleans when Kristen Doute accused Schwartz of having sex with a girl behind Maloney's back in Las Vegas. He eventually confessed that he made out with the girl Doute mentioned.

"She also has issues over her weight gain," the insider added.

Maloney previously revealed that her weight began concerning her after Lala Kent and James Kennedy began calling her "fat." Kent and Kennedy even commented on her lack of a "summer body" during the season five premiere episode.

Breaking Celebrity News previously reported that the couple was in rocky territory after Jax Taylor teased that they split via Twitter. Maloney's mom, Teri, assured Breaking Celebrity News that "everything is wonderful" between them — but their friends continue to think otherwise!
