It was another day of filming for Braunwyn Windham-Burke, and The Real Housewives of Orange County rookie had her beverage ready to go. So, what's in her red Solo cup, you wonder? We think we have our answer. 

In a September 10 Instagram post, the super mom of seven shared a snap of herself getting ready to go on camera at Orange County Production Studios. In addition to makeup, the table in front of Braunwyn held a couple of red cups and also a couple cans of Perrier.

Mystery solved! This mama stays hydrated on sparkling water while filming. Braunwynn has told The Feast before that she's not the type to get liquored up too often, and that she doesn't keep alcohol in the house. 

Sorry, nothing scandalous to see here: 

Cheers!
