The musician and TV presenter will design a range of clothes and "fabulous funky accessories" called Baby K.
The range, which will launch at the end of August, will cater for children up to the age of three.
Klass gave birth to daughter Ava five months ago and is delighted to put her knowledge to good use.
She said: "I am so excited about my Baby K range. As a new mum I have used my first-hand experience, with other mums in mind, to help design a stunning variety of products - and who better to do this with than Mothercare, the mama of all stores!"
Baby K is the first celebrity line to be sold by the high street chain.
