Katie and her long-term partner welcomed their little girl into the world in March but is now back at the helm of her Katie Piper Foundation.
Yesterday (1 July), Katie joined a group of school girls from Berkshire, who were holding a fundraising event to raise money for the charity.
The mum-of-one looked pretty in pink after teaming a Katie Piper Foundation T-shirt with a bright cerise skirt from high street store Oasis.
Katie topped off her look with a simple pair of white heeled sandals from Boohoo and she kept her long hair in loose waves.
What a yummy mummy!
Katie set up her charity after she was involved in a horrific acid attack in 2008.
The Foundation supports burns victims through special workshops, classes and social activities, and is understandably very close to Katie's heart.
After visiting Queen Anne's School in Reading yesterday, Katie said: "First day back at work after maternity leave.
"Very uplifting evening to see how hard the @QASCaversham students had worked to lay on such a great event for The Katie Piper Foundation!
"Thank you to everyone involved!"
