Christina Haack’s Las Vegas birthday celebrations were shared on Instagram by Heather Rae El Moussa on Monday, July 21. Haack and Heather Rae were joined by their partners Christopher Larocca and Tarek El Moussa for a whirlwind 24 hours in the city.

Heather’s post featured several photos of herself, Tarek, Haack, and Haack’s boyfriend, Christopher Larocca. The group and more of Haack’s friends rang in her 42nd birthday with a day at the pool and a night dining out at a fancy Sin City restaurant.

For all the heightened drama that’s part and parcel of reality TV, one of the rarely exhibited pockets of peace revolves around Tarek El Moussa and Christina Haack, who somehow turned being friendly exes and successful co-parents into a career move.
