Don't think so. She said her goodbye and she's put it in the past, I'd love it but I feel she done the right thing and shouldn't. Maybe when the show does finally come to an end, or like an anniversary show in the future. It'd be special that way, not just a random ep on a random series.
Plus I'm pretty sure she is actually busy. She's got her whole diet/fitness business going, a new adventure TV series coming up and Long Lost Family in the Summer.
