"Feeding my baby bear before I go to work," Katie captioned the photo.

Hampshire-born Katie, 31, recently got engaged to her long-time love and Belle's father James.
"So excited to tell you all.............. I became someone's fiancé last night!" she tweeted. "I'm engaged to be married :)".
It is thought that Katie's carpenter partner popped the question during a romantic homecooked meal as she had been praising his culinary efforts on social media the evening before she announced the happy news.
"Pretending we are going out for dinner! Cooking 3 course meal, dressed in our best clothes- all taking place at our kitchen table! Parents night in/out #nobabysitterneeded," she tweeted. "I think my boyfriend has potential as a chef! Baked Cod with Capers."
Katie introduced her daughter in HELLO!
Katie, who suffered a horiffic acid attack at the age of 24 when her modelling career was just taking off, is in a very positive place.
"When I look in the mirror, my scars no longer upset me," she revealed. "They just remind me I am stronger than the person who tried to hurt me. We all have scars, whether they are on the skin or the soul. Remember only those who survive wear scars. Next time you look in the mirror, repeat to yourself I'm proud to be a survivor."
