The blonde beauty was pictured clutching on to her 11-month-old and supporting her from behind as baby Belle stood on her own two feet.

Katie, 31, welcomed her firstborn in March of last year with her carpenter boyfriend James. The couple then announced their engagement in December, with Katie taking to Twitter to share the joyous news. "So excited to tell you all.............. I became someone's fiancé last night!" she tweeted."I'm engaged to be married :)".
A couple of weeks later Katie posted a selfie of herself and James, in which her beautiful round-cut sparkler can be clearly seen on display. "He put the official ring on it!" wrote Katie.
The charity campaigner, who survived a brutal acid attack in 2008, is famously private about her family life, but took part in an exclusive photoshoot and interview with HELLO! magazine shortly after welcoming her first child via Caesarean.

"I am so overwhelmed with happiness," Katie told HELLO! magazine. "I literally can't stop looking at her, she's just beautiful. People used to say to me, 'It's a love like no other,' and I understand that now. She's so precious and I just feel so incredibly blessed to have her. She's our world."
The philanthropist, who has undergone more than 100 operations as a result of the attack, added that giving birth in a hospital brought everything full circle.
Katie said: "To have had my own life saved in hospital and then to be there giving life to this precious little person, I thought, 'This is why, this is what it's all about.' I already felt grateful that, after the attack, I'd managed to restore a life, have a job, friends, a social life, and I thought, 'You can't expect to have everything, this is enough'.
"Then, to meet and fall in love with James, a man I knew I wanted to have a baby with and who makes me so happy, and now to have Belle – it's just amazing."
