On Saturday, Katie revealed that she is set to marry James after he popped the question during a romantic dinner at home the previous evening.
The inspirational star gushed: "So excited to tell you all.............. I became someone's fiancée last night! I'm engaged to be married :)"
Earlier today, fresh from her exciting weekend, Katie was back to work and filming her new series of C4 show Bodyshockers after travelling up to Scotland.
Despite the freezing temperatures and blustery winds, the mum-of-one looked seriously happy as she posed for two Instagram pictures. And, if you look closely, you can almost make out Katie's engagement ring in one of the shots!
Katie told her followers: "Filming at the top of Dundee Law! Trying to talk quickly because it's practically sub zero!!"
She added: "Forgot my gloves and can't feel my fingers! #cold #Scotland."
Careful, Katie, fingers shrink when it's cold outside. Mind you don't lose your precious new rock!
In 2008, Katie suffered severe burns in a horrific acid attack which had been organised by her ex-boyfriend. Since then, she has undergone numerous operations and has worked hard to improve the lives of fellow burns victims.
Katie set up The Katie Piper Foundation and, last week, Simon Cowell, Mel B and Cheryl Fernandez-Versini attended a ball held to raise money for the charity.
In March, Katie and James welcomed their first child together, a baby girl called Belle Elizabeth.
