Brummy-born, Alex showed off his brand new set of teeth last week after deciding to treat himself to some shiny veneers and why not?

Uploading a snap of his gnashers on Instagram, the tattooed star wrote: Massive thank you to @ask_the_dentist for giving me my dream smile.

But unfortunately some of the stars 1.1 million followers werent a fan of his bright while smile, and went on to criticise Alex in a BIG way.

One fan ranted: I LOVED your teeth. They were what made you so gorgeous and were so unique to you. Im gutted. But you still look hot. Just a bit more generic sadly!

If youre considering getting them done, be warned its so hard to eat afterwards. I couldnt bit into a crisp or a crust of bread.

And when I tried to eat soup, it kept dribbling out of my mouth because it was numb and I couldnt feel it. So attractive, ha ha! LOL.

Were pretty sure these two are going to have the whitest teeth in Essex.
