Bear Grylls has shocked his fans with his latest look, following an appearance on ITV's Good Morning Britain.
Revealing his new facial hair, which was labelled a 'porn star moustache' by viewers, he admitted the new look wasn't a permanent fixture, and confessed he was growing it to show his support for Movember.
Movember is part of a campaign month which encourages men to get sponsored for not shaving their beards, in a bid to raise money for prostate and testicular cancer, as well as raising awareness around mens mental health.
Yet, it managed to distract hosts Ben Shepard and Charlotte Hawkins, as well as those watching at home because many took to Twitter to express their confusion over Bear's new look.

We had to take a double look when she posted this photo in a blonde wig. She's giving off serious Kim Kardashian vibes, right?
Stacey Solomon
Loose Women panellist Stacey Solomon says her hair is 50% grey roots and damaged ends, which is why she invested in a wig. In true kooky Solomon style, she called her wig 'Suze'. We've always loved Stacey for her down to earth nature and honest attitude, especially when it comes to body image and parenting.

Now, Stacey loves experimenting with new looks like retro curls and rose gold tints. She also posted a hilarious video of washing Suze the wig in the bath.

Sinitta wears a weave to maintain her brave styles, and it was reported that a man pulled the weave straight off her head outside a London nightclub. We can't be-weave anyone would be that mean.
Christine Lampard
TV presenteR Christine Lampard wanted to see if blonde's really do have more fun...

TV sweetheart Scarlett Moffatt took the plunge and went for a short, sharp shoulder-skimming bob.
