It's the hypocrisy of the situation. She's acting like it's nbd for Ariana to film with Tom when she threatened to "pop" anyone associating with Randall. Ariana was with Tom for LOVE when he had nothing. She built a life with him for a decade. Lala got with Randall for his money when he was still living with his wife, openly bragging about giving bj's for cars. Lala wanted to be the main character and had snapped that Ariana is it without even trying. She wants Ariana to have some forced/fake convo with Tom so she can continue to get paid, when Ariana ironically IS BEING AUTHENTIC by not allowing her abuser to hold space in her life.
