The budding fitness guru has a rocky history with Peterson and says her comeback created drama.
“Lauri came back to stir up some sh*t, she really did,” Barney dishes to Housewiveshoedown.com.
Peterson was always the most reserved of the pack but her return this season turns up the heat. Bravo claims she will “reveal shocking information that will rock one of the wives’ worlds.”
“I think Lauri came back to try to get her job back,” Barney tells the website.
“So she definitely stirred up a lot of stuff that even me, I probably wouldn't have gone there,” she added.
Barney says Peterson shows a different side this season.
“So it will be interesting to see a different Lauri because before we have always in the past have this Lauri that was very conservative, this is like shit talking Lauri.”
The new season of "Real Housewives of Orange County" airs Apr. 1 on Bravo.
