Thing is, at the end of the day, her and Gorks have a mortgage to pay. She's only a local DJ realistically (with a book deal and the ITS deal, both of which probably don't pay excessively), and the pro dancers don't get a lot compared to the celebs, hence the ads. He's not even headlined his own tour.
Times are getting harder and maybe she just does it to put money in the bank. We've all been there, done it. She's got aging pets, maybe vets bills are getting more.
To some, maybe she is selling out. Maybe she's just protecting their future. I enjoy the family stuff with Mia (she's got a fab accent!), Esp with her crush on Will Mellor
