“We don’t talk,” she said. “We’re just really different. She doesn’t understand me and I don’t understand her.”

For her part, Aimee has talked about her complicated relationship with siblings Kelly and Jack in a 2015 interview with the Independent.

“I wouldn’t say there is an ease between us, but there is an acceptance. Do we socialize? No,” Aimee said.
