As Cartwright films the reality series, A-listers, including the "Same Old Love" singer and the "Karma" vocalist, have been following along with the drama. "That was awesome," she says of Gomez's admission that she and Swift chat about The Valley and Vanderpump Rules. "People were making memes of them whispering to each other and it was like, 'Did you hear Brittany filed for divorce?' I thought that was so funny. But I knew Selena was a fan because she had visited TomTom in the past."
"I also thought Rihanna talking about The Valley on the red carpet at the Fenty show was incredible, " the mother-of-one adds. "She was like, 'I relate to this!' And I said, 'Rihanna relates to me? That's crazy!'
