Megan Thee Stallion is officially in her acting bag! Source: The Fall and Rise of Reggie Dinkins / NBC Universal Back in February, NBC announced that Megan would be guest-starring on The Fall and Rise of Reggie Dinkins. The network released a trailer for the episode, showing Meg as Denise, a recently divorced mother who strikes up a "flirtation" with Daniel Radcliffe's character, Arthur Tobin. In that trailer, Arthur can be seen at a park as Denise watches him in the background, wearing a postal service uniform.
