Real Housewives of Miami's Marysol and Adriana's friendship goes up in flames. Here's what went wrong

The Real Housewives of Miami stars have been embroiled in a bitter feud that started when De Moura found out Patton was…

The Real Housewives of Miami's fifth season had no shortage of drama, but the feud between Adriana de Moura and Marysol Patton took the cake. The two OGs returned as "friends," but their rift caused enough of a stir to earn them spots as main cast members.

The Real Housewives of Miami stars Marysol Patton and Adriana de Moura.

It all started when de Moura claimed that Patton's ex-boyfriend made a pass at her and wasn't in love with the former public relations specialist. Patton was hurt that her friend would bring up something from the past and refused to hear any excuses.

De Moura then compared her ankle injury to Alexia Nepola's son's car accident, which led to permanent brain damage, further inflaming the group. The season 5 reunion ended with no resolution, and Patton declared that she would never be de Moura's friend again.

But what caused the rift in the first place? Patton claims that it was de Moura's jealousy over the cast's appearance on "Ultimate Girls Trip." When Nepola agreed, Patton continued, "The minute she found out ... I told Alexia, 'Don't tell the girls because, somehow, Adriana will find out.' We knew all the girls would be happy for us. But we knew Adriana would be pissed."

Their feud only escalated from there, with de Moura handing Andy Cohen a letter during the reunion written from the point of view of Patton's liver, which Patton called the "worst punchline on the planet." She's not ready to let go of the prank, and de Moura has a lot of making up to do if she wants to repair their friendship.

Will these former friends ever make up? Or will their feud continue to be one of the most explosive in Real Housewives history? Only time will tell.
