Blaineley is obsessed with gossip and fame. She wants more than anything to obtain a "juicy" story and attempts to delve into topics that could potentially cause a scandal. When she first appears in Celebrity Manhunt's Total Drama Action Reunion Special, Blaineley is depicted as enthusiastic and friendly; however, her true colors are eventually revealed when she starts hosting Total Drama's Aftermath show.

On the aftermath show, Blaineley demonstrates that she is conceited, mean, and willing to do whatever it takes to remain in the spotlight, including sending Bridgette to Siberia and lying about her real name. When she joins Total Drama World Tour as a contestant, it doesn't take long for the others to start hating her, but a different side to Blaineley is shown when she is paired with Owen in Niagara Brawls. Through an unlikely friendship, Owen helps Blaineley let loose and focus less on her public image, proving that she isn't entirely bad after all.
