While the buzz around the three finalists intensify, mobile brand Three have given Mary's hometown store a makeover, or shall we say, cake-over!
The High Wycombe store have replaced their display phones with actual cake equivalents to mark tonight's grand occasion.
Yes, Bake Off fever is well and truly underway!
We're sure judge Mary would be impressed with the hard work and dedication gone into baking an iPhone 6 or Samsung Galaxy, right?!
Of course, the most important thing is how good it tastes. We can just imagine her tucking into the mobile cake and giving feedback on the whether the right ingredients and filling were used.
The sixth series of GBBO is coming to an end tonight, where after 10 weeks, the contestants have been whittled down and tested on their baking skills.
The final three bakers going head-to-head on tonight's show are:
1. Nadiya Hussain, 30, from Leeds.
2. Ian Cumming, 41, from Cambridgeshire.
3. Tamal Ray, 29, who grew up in Hertfordshire.
