The ladies of Real Housewives of Orange County left Mexico in one piece, but tensions after Tamra Barney’s epic bachelorette weekend remained high. Lydia McLaughlin’s salsa dancing party proved to be a fun bonding experience that also led to some uncomfortable confrontations.

Not only did Lydia and Slade Smiley go at it, but Tamra and Gretchen Rossi had a moment of awkwardness after Gretchen voiced her concern over Alexis Bellino being invited to go wedding dress shopping with Tamra.

So will we find out whether Tamra’s shopping excursion will leave the ladies divided in a new episode of Real Housewives of Orange County tonight?

Not so fast! We won’t be seeing Real Housewives of Orange County Season 8, Episode 13 tonight, but Bravo has a different treat in store for fans of the show.

To celebrate the 100th episode of RHOC, the network is airing a two-hour documentary special that details how the Real Housewives franchise got started and features in-depth interviews with Real Housewives of Orange County cast members past and present. That means viewers will get to see former Housewives like Jo De La Rosa, Jeana Keough, Tammy Knickerbocker, Lynne Curtain, and the many sons and daughters of the RHOC women.
