Stassi Schroeder is returning to Vanderpump Rules next week, and Lisa Vanderpump isn't completely thrilled.

'Vanderpump Rules' Stassi Schroeder & Boyfriend Parted Ways During Season Four?

For the last couple of seasons, Schroeder's relationship with her former boss has been strained, and despite Schroeder's claims of having changed since last year, the Real Housewives of Beverly Hills star isn't convinced.

"Before she came back into the mix so to speak, it was absolutely a prerequisite — not just for the filming but before she came back into the whole circle — to apologize to me," Vanderpump explained to The Daily Dish on Friday. "And she has this arrogance about her."

'Vanderpump Rules' Stassi Schroeder Doesn't Think It's Fair That She Wasn't Included In Cast Hawaii Trip

"She still even says recently or says on the show, 'Well Lisa only ever gave me a job as a waitress.' I called bull on that because we all know, breaking the fourth wall, I gave her many, many opportunities," Vanderpump explained, citing her role as an executive producer on Vanderpump Rules. "I made Stassi Schroeder a name that nobody had ever heard of. So, for that, I think humility is an important factor of being successful."

"She said to me [she changed], but then when I see the arrogance on the show, I think the day I really will see growth [is] when you see humility. And I think humility is an important factor in growth," Vanderpump added.

Stassi Schroeder returns to Vanderpump Rules on Monday, Jan. 25, at 9 p.m. on Bravo. Check out a sneak peek at the upcoming episode below.
