Now in a preview for the show, she explains how she's gone from mad parties to complete loneliness as she struggles to come to terms with her win.
Her granny Anne can be seen saying to the cameras: "She [Jane] said 'Nanna I've got the same numbers on the telly as I've got on my ticket. I'm a millionaire'."
She added: "I said 'that's like giving somebody a gun, eh?'"
Jane reveals the first thing she bought was a Louis Vuitton handbag - oh, and of course her pooch."
