Find out why Katie Maloney has Jo Wenberg feeling like she’s “literally on planet Mars” during the Vanderpump Rules Season 11 reunion.

lly Lewber and Jo Wenberg are joining the rest of the Vanderpump Rules cast on the Season 11 reunion when Part 2 airs on May 21, but it’s safe to say that the latter is already making quite the impression in the above preview.

The sneak-peek features Jo and Tom Schwartz attempting to dissect their complicated relationship, but the pair’s explanation of what exactly went down between them only leaves Tom’s castmates — as well as reunion host Andy Cohen — feeling even more confused than before.

Were Tom Schwartz and Jo Wenberg dating during Season 11?

Jo says that she and Schwartz were “basically, like, dating” during filming for Vanderpump Rules Season 11. Schwartz, on the other hand, only admits to “hooking up” with Jo “sporadically.” How sporadically? “Once [or] twice a week.”

What does Katie Maloney say about Jo Wenberg at the reunion?

Katie Maloney and Jo butted heads several times over the course of Season 11, but during Part 2 of the reunion, Katie admits she’s since realized that Schwartz was “breadcrumbing” Jo.

“I felt really bad when I was watching it because I was like, ‘Oh my god,'” Katie says before turning to Jo herself. “I felt really bad for you because it seemed like he was being very elusive and you saw the relationship very differently.”

Katie also tells Schwartz, “You’ve been giving the relationship and boyfriend experience, so no wonder why she would assume that you were in a relationship.”

Jo, for her part, is stunned. “I’m literally on planet Mars right now,” she says after Katie shows empathy toward her. “What just happened?”

The Vanderpump Rules cast’s reaction to Jo Wenberg and Tom Schwartz at the reunion

As Jo and Schwartz continue to unpack their relationship, several of his castmates express their bewilderment over the pair’s admissions.

Lala Kent, for example, says, “What the f-ck is going on?” after Jo and Schwartz give conflicting answers about whether or not the said “I love you” to one another.

“This insane,” adds Ally Lewber.

Then when Schwartz claims that he and Jo “were always very transparent” and “had a great line of communication with each other,” Scheana Shay steps in to tell him, “It didn’t seem like that watching all of her interviews and everything she said.”

Andy agrees, noting, “It didn’t seem like it watching the show.”

Katie delivers one of the final lines, telling her ex-husband, “You were displaying some, what we call, f-ck boy behavior.”
