Katie, who is expecting her first child with her boyfriend of two years, was pictured in a pretty cerise dress at Best magazine's Bravest Women Awards in London.
The star, 30, teamed her simple but cute frock with a pair of black peep-toe boots and she accessorised with a small gold shoulder bag. Katie was even rocking a red pedicure painted by her fella!
Katie, who was seriously burned following a horrific acid attack, had a great night and was delighted to be one of two women to win a Lifetime Bravery Award.
Her friend Simon Cowell even recorded a special personal video message to congratulate her on the achievement.
"I got to meet you a few years ago and you were actually an inspiration to me," Simon said.
"After what you went through and having got to know you, you're one of the most bravest people I have ever met in my life."
He continued: "You have an incredible attitude, you are a fantastic role model for everybody and what is most important is you've used what you've gone through to help other people.
"You've given them hope and I adore you, Katie. Everything that's coming your way now you thoroughly deserve."
Taking to Twitter after the star-studded event, held at the Crowne Plaza in London's St James, Katie told fans: "Wow what an incredible night I've just had as very unexpected!
"Fantastic evening @BestMagDaily #BestBravestAwards then totally shocked 2 win Lifetime Award with most touching msg from @SimonCowell Thank u."
