Scheana Marie is spilling the tea!

The Vanderpump Rules star revealed that although the ladies of the hit Bravo reality TV show are friends, they still get jealous of each other. She opened up about what really drives the feuds between the co-stars during a radio interview.

“No one admits this other than me, but I think we all are very competitive with each other,” Scheana said during her appearance on The Tomorrow Show. “We aren’t always genuinely happy for each other when someone else gets an opportunity. So I think that’s something subconsciously, too, that makes us fight.”

The 31-year-old — who recently opened up about her divorce from her estranged husband Mike Shay — also said the show’s producer, Bravo TV exec Andy Cohen, definitely plays favorites with the cast.

But during last Monday’s episode of Andy’s show Watch What Happens Live, he continued to stir the pot when he asked Pump Rules star Ariana Madix about her recent feud with co-star Stassi Schroeder, since Ariana told Stassi that she didn’t “give a f–k about her” during last week’s episode.

“I don't,” Ariana said. “I don't understand the entitlement that she has in this group…so sorry, not sorry.”
