The twins shared the role until the end of April of that year, however Leah tragically died from cot death during the following month.

After leaving school she enrolled in a drama course at Manchester College of Arts and Technology, but did not complete it due to financial pressure.
She made a return to acting and appeared in a 2009 stage production of Lady Chatterley:Cyber Charades, although it appears to be her only credited role since this time.
