The Real Housewives of Orange County are back!

The first ladies of Bravo are making their triumphant return this summer — and PEOPLE has the exclusive First Look at all the fun (and fighting!) ahead in season 12.

Returning for another round at bat is gym owner and body-building champ Tamra Judge, feng shui guru Shannon Beador, new mom Meghan King Edmonds and bubbly Bible-lover Lydia McLaughlin — whose RHOC return comes after a run on the show’s eighth season. (No word whether her pot-smoking mom Judy will be back as well, but fingers crossed).

Of course, the O.G. of the O.C. Vicki Gunvalson is whooping it up again in Coto de Caza. Bravo’s longest running-Housewife has been with the show since it premiered in March 2006 (and subsequently spun off eight Housewives franchises in the U.S. alone).

But Gunvalson isn’t the only Housewife this season making history. New Housewife Peggy Sulahian‘s premiere on the show makes her the 100th Housewife in franchise history. And boy, does the Armenian-born brunette jump into the action. The wife of a custom wheel mogul with two teenage daughters and a 9-year-old son at home, Sulahian is introduced to the Housewives through McLaughlin — though she doesn’t appear to do the best job making friends.

“You’re a f—ing bitch,” Edmonds screams at her in one heated scene.

“You want to throw a bomb, I’m going to throw a nuke,” Dodd shouts at her in the same clip.

Sulahian isn’t fazed. “I’ll make you look like a fool,” she says threateningly later.

There seems to be a fair share of fireworks all around — including a rowdy group trip to Iceland, yet another medical evacuation in an ambulance and the closest thing to a Teresa Giudice table flip we’ve seen yet.

Edmonds is learning that motherhood isn’t all its cracked up to be, especially with husband Jimmy at home being an overbearing father. Dodd’s rocky relationship with husband Michael remains complicated. And what was left of Gunvalson’s once-close friendships with Beador and Judge is still in ruin after last season’s shocking accusations during the Ireland bus ride from hell — leaving stress on all sides and McLaughlin stuck trying to play peacemaker.

Gone from the action this season is RHOC star Heather Dubrow, who announced in January that she would be departing the series after five seasons.

There is a treat for RHOC superfans, though, in the form of a cameo from former Housewife Gretchen Rossi, who shows up and once again fuels questions about Judge’s husband’s sexuality.

Check out the full trailer above for how that question goes over and other juicy moments from the new season.
