...but she proved that she's just like the rest of us when it comes to dealing with negative comments and anxiety and she served up some sound advice, too!
On Sunday evening (7 August), Gorgeous Katie took part in a Twitter Q&A and she got real honest about how she manages to brush off any negativity that might get thrown her way.
Desperate to know how Katie avoids letting jibes and feeling unassured get to her since appearing on television, one fan asked,
"How do you deal with insecurities and trying to put comments behind you? You always seem so confident!" which seemed to hit a nerve with the star.
"Confidence is beauty," the stunner wrote back, "and if you don't love yourself no-one else will love you #truestory." She also took to Instagram to promote self love and captioned a new selfie, "Haters never win!"
Of course, it wasn't long before the likes came flooding in for Katie who encouraged her fans and followers to be happy in themselves without worrying about what other people think.
"You're beautiful inside and out," wrote one of her Insta-followers, while another said, "Looking amazing Katie. Such a lovely girl, great personality."
N'aw, you guys!
During the Q&A, Katie also mentioned that she would absolutely love to jump on the mermaid hair bandwagon a la Gogglebox's Scarlett Moffatt and Love Island's Hannah Elizabeth but doesn't think she can pull it off!
"I like silver hair but I don't think I have the balls! Who knows!" she wrote. And would she ever channel her inner Ariel with red locks like pal Jessica Hayes?
"I couldn't kill it like her. [I'm] a brunette baby!"
